794126bfdb Port "Mein Zimmer" - the Home Assistant room panel 
The second of the web front-end's three pages. Lights get a toggle, five brightness
steps and six colours; shutters get four presets, up/stop/down and a window that
reflects the position Home Assistant reports. Its own violet hue rather than the
player's teal, so the two pages read as siblings rather than one bleeding into the
other - the same reason room.css has its own tokens.

The backend keeps Home Assistant's URL and token and relays the calls, so this client
learns only which entities exist, exactly as the browser does. A 404 from GET /api/ha
means Home Assistant is not configured, which is a normal answer: the tab simply does
not appear.

Polled, not subscribed, and only while the page is on screen. HA's own auth-and-
subscribe websocket is more machinery than a room panel needs, and a lamp's state is
not worth a request every 2.5 seconds when nobody is looking at it - this device has a
music player to stay out of the way of. A tap patches the entity locally and records
when; a poll that was already in flight when the patch landed is dropped for that
entity rather than putting the lamp back to "off" until the next one catches up. That
reconciliation is the one non-obvious thing in useHomeAssistant.ts and it is carried
over for the same reason.

Nothing on a shutter card animates locally. A real cover reports its own movement and
position, and a client-side guess at where it will end up is precisely what would
fight with that - the design mockup animated it because it had no backend to ask.

Two additions beyond a straight port, both because a kiosk has no pointer:

CTRL+TAB cycles the pages. The web's tab rail is pointer-only, which sits badly with a
front-end whose README claims every screen is reachable from the keyboard. Plain TAB
was already the group cycle, and CTRL+TAB is the idiom for the outer one everywhere
else.

--page opens directly on a page, which a kiosk may well want and which is the only way
in with neither keyboard nor pointer.

Verified against the real Home Assistant: the shutter reported open and the lamp off,
and both drew that way. Nothing was switched - those entities are hardware.

ec9d617ad8 Vendor Nunito as a TTF so the device renders in the right face 
Slint cannot read woff2, which is the only form web/public/fonts/ carries, and Raspbian
has no fonts-nunito to install instead - so the device was going to fall back to
DejaVu Sans, which is not what any of this was drawn in. The upstream variable TTF
(SIL OFL, weights 200-1000) is small enough to vendor and covers every weight the
design uses, including the 800/900 the headings lean on.

SLINT_DEFAULT_FONT takes one file and makes it the primary font. shell.nix now points
at this copy rather than at nixpkgs' own, so development and the device render from the
identical file, and the binary falls back to finding it beside the executable when
neither the dev shell nor the device's launcher has set the variable.

6ccb3e458f Add a native Slint front-end for the music player 
The React UI is sluggish on the kiosk and the reasons are browser-shaped: a compositor
deciding what gets its own layer, a requestAnimationFrame loop repainting the viewport,
and a JPEG decode per album card per cold start. The last three commits chased that
through the service worker and the cover pipeline. This is the other direction - the
same backend, the same layout, the same German copy, without a browser.

Browse and play only. The typing game, the room-lights page, parent mode and the
IR-remote assignment stay web-only, and nothing here touches python-backend.

Four things carry the performance claim, in rough order of how much they should matter:

Covers are downscaled once, ever. The backend serves one size - 640px on the long edge,
no ?size= - and a grid card is 180. src/covers.rs fetches each cover once on a worker
thread, resizes it, and writes a JPEG thumbnail to ~/.cache/musicmouse-slint/covers/.
Two tiers and only two, which is what makes the cache worth keeping: a per-widget pixel
size would give each album a dozen near-identical files and a fresh decode for each. The
cache is dropped when the websocket announces a rescan, because that is the one moment
the backend rewrites the art behind an unchanged cover URL - the trap sw.js had to learn
about the hard way.

The grid is virtualized. Rust hands the UI the album list pre-chunked into rows and the
view puts those in a ListView, which instantiates only what is on screen. A flat list of
660 cards gives it no rows to skip, hence the chunking. Same purpose as
content-visibility: auto on .grid > .card.

The progress bar animates between the 2 Hz pushes rather than running a clock, so
interpolation costs a property evaluation per frame on the render side and there is no
equivalent of usePlaybackClock. It is suppressed for the frame a track changes on, so a
new track jumps instead of sliding across two unrelated positions.

Nothing on screen animates by itself. The ambient canvas is not ported, for the reason
lib/lowPower.ts already gives: a loop repainting the viewport is a floor you cannot get
under while it runs at all.

The device must not use FemtoVG. On Mesa V3D it draws every runtime-loaded Image as
solid black (slint-ui/slint#11785, open), which here means every album cover; Skia and
the software renderer are unaffected. So `kiosk` is linuxkms + Skia and FemtoVG stays
the default only for desktop development. Both profiles are verified to build; the kiosk
binary links libinput/libgbm/libdrm and no X11 or Wayland at all.

lib/search.ts, lib/keyboard.ts and lib/format.ts were already pure functions with their
own tests, so they port across as pure Rust with theirs: 43 tests, no window required.
The .slint files are layout only - nothing in them formats a number or picks a word.

Verified against the real 660-album library rather than a fixture. tools/headless-shots.sh
renders the UI inside a nested headless compositor and grabs a frame per screen, which
is how that was checked on a machine whose session was locked; a Slint window needs a
real compositor, and under bare Xvfb nothing maps at all.

83d16e0058 Take the service worker off the cover path, and cut cover art to 384px 
Search was still stalling for seconds a keystroke. A trace across five keystrokes said
the renderer main thread was blocked for 9.4 s in a single task with *zero* V8 samples
inside it - no JavaScript ran at all. What ran instead, on the worker pool during those
same 9.4 s: ImageDecodeTask 7.6 s, RasterTask 1.7 s, and only 229 ms of actual "Decode
Image". The main thread was waiting on cover bytes, not computing anything.

Two causes, and the first one was mine. The stale-while-revalidate handler added earlier
today made every cover do a Cache Storage read *plus* a network fetch *plus* a cache
write, all serialised through one worker thread. Measured with
Network.setBypassServiceWorker: worst keystroke 5580 ms through the worker against
461 ms without it. So covers no longer go through the worker at all. That costs nothing
here: this worker only registers on localhost or over HTTPS, which on this setup is the
kiosk on the device itself, where the backend is the same machine and a cache lookup is
strictly more work than asking for the file. The shell caching, which is what makes it
installable, stays.

The second is that decode cost goes with pixel count, and 640 px was headroom for a
tablet at devicePixelRatio 2 that nobody had asked for. A browse grid paints a card
132 px wide; the largest any screen asks for is 340. At 384 px, typing "conni" over 343
albums, keydown to painted, three runs:

  before   3735,  270, 5580,  88,  57 ms
  after     873,   75,   17,  24,  26 ms

`shrink_cover` never scales art up, so dropping the limit cannot be applied by
re-reading the cache - only by going back to the original art. _INDEX_VERSION 6 does
that: the index is discarded and every album is scanned again through store_cover.

ebab03b700 Cache every cover, not only the ones pulled out of tags 
The downscaling landed and the device kept serving 1920px art, because _cover_for has
two branches and only one of them went through the cache. An album with a cover.jpg
already sitting beside its audio - which most of this library has - had its `cover`
point straight at that file, so FileResponse served whatever the internet had given it.
The cache directory was full of tidy 640px files that half the albums never used.

Both branches now store through the cache, in _cover_for and in _cover_for_episode
(sidecar and shared-folder art alike). The undownscaled bytes still come back alongside
the path, because colour extraction wants the real thing.

That re-points `cover` for every album, but only for albums that are actually rescanned,
and the scanner reuses anything whose fingerprint is unchanged - so _INDEX_VERSION goes
to 5. An index from 4 is discarded and rebuilt, which is what that mechanism is for and
is cheap by design.

Two tests asserted `cover == <the library file>`, which is precisely the behaviour being
changed. The episode one was also checking something real - that an episode's own
sidecar art beats the show's shared cover - and both covers now live under their own
album id, so it reads the colour back out of the stored file instead of comparing paths.

3fea56d4e1 Stop cover art going stale in two caches at once 
Shrinking the covers changed nothing on the device, twice over, because two layers were
independently serving the old bytes and each had the same wrong premise written into its
comment: that a cover is "content-addressed by album id". The id addresses which album
the art belongs to. The bytes behind the URL change whenever the art is reprocessed.

The backend sent `public, max-age=604800`, so every browser that had loaded the page in
the previous week kept decoding the 3000px original out of its own disk cache without
asking. It now sends `no-cache`, which does not mean "do not store" but "revalidate
before reusing" - the file stays cached and the usual answer is a 304.

The service worker cached covers cache-first on a URL that never changes, which means a
client could serve a stale cover for ever; bumping the cache name fixed today's covers
and would have had to be done again for the next batch. It now does
stale-while-revalidate: the cached copy is returned immediately, so a grid of album art
still never waits on the network, and a fresh copy is fetched behind the page for next
time. Neither layer needs a version bump when art is reprocessed again.

The revalidation is off the paint path entirely, which is what makes `no-cache`
affordable here: the service worker answers first, the network call happens behind it.

e1c10f5408 Retire the service worker's cache of the old, huge cover art 
A DevTools trace recorded on musicdolphin put the whole question beyond argument:

  ImageDecodeTask      29,939 ms  x20   (~1.5 s each)
  Decode LazyPixelRef   3,924 ms  x20
  Decode Image          3,530 ms  x22
  Paint                    99.7 ms
  Layout                   77.3 ms
  all app JavaScript      <400 ms  across 22 seconds

Image decoding is not the largest cost on that page, it is very nearly the only one.

The covers should already have been small - the backend downscales to 640 px now - but
the page was still decoding them at 1920, 1600, 1400 px, with deliveryType
"cache-storage" on every one. The service worker caches cover art cache-first, keyed on
URL, on the premise that it is "immutable per album id". The id did not change; the
bytes did. So every client that had ever loaded a cover kept serving the 3000 px
original from its own disk and never asked the backend for the new one.

Renaming the cache is the retirement mechanism the worker already has - `activate`
deletes every cache that is not one of the two current names - so COVERS becomes v2,
with a note saying that changing how covers are produced means bumping it.

0ef5a04cb9 Downscale cached cover art, and stop every animation loop under ?pi=1 
Covers. Art out of an ID3 APIC frame is sized for a record sleeve: this library
averaged 3000x3000 and 580 kB per cover, 140 MB across 284 albums. The browser was
decoding nine megapixels - around 36 MB of bitmap - for every cover it painted, to show
it in a 185 px card, on a Pi with 2 GB of RAM. The largest any screen in this app asks
for is 340 px (the play view), so cache.store_cover now downscales to a 640 px long
edge, which leaves room for a tablet at devicePixelRatio 2 and cuts the decode about
twentyfold. Pillow was already a hard dependency, for colour extraction.

scan_library reuses an album whose fingerprint is unchanged without re-reading its
tags, so covers already on disk would never be rewritten - hence shrink_stored_covers(),
a pass at the top of a scan. Reading a JPEG's dimensions only parses its header, so
after the first run it costs one small read per album. Art already small enough is
returned byte-identical rather than re-encoded, so repeated scans cannot slowly grind
it down, and anything Pillow cannot read is passed through untouched: a cover that is
too big is a performance problem, a cover that is missing is a visible one.

Animation. Halving the ambient canvas to a quarter of the pixels at 30fps took it from
53.5% of a core to 25%, and 25% was still not good enough to use. A requestAnimationFrame
loop repainting the viewport is a floor you cannot get under while it runs at all, so
?pi=1 now switches it off outright rather than thinning it, along with the decorative
CSS loops, the view transitions, the typing game's bubbles and its next-key pulse. The
pets stay on screen but hold still, through the same path prefers-reduced-motion already
took - taking the animation away is the point, taking away what she earned is not.
.stage keeps its own static gradient, so there is still a sea behind everything.

Both blurs on the panels stay on. Dropping those measured five times worse.

3cdad1e714 Stop rendering album cards that are off screen, and split card blur from panel blur 
Searching a single letter over a real library puts 340 cards in one grid, each with a
cover image, a shadow and a backdrop blur, all of them live whether or not they are on
screen. On musicdolphin that saturated the renderer badly enough that a DevTools
Runtime.evaluate could not be scheduled on the main thread inside 30 seconds, which is
a fair description of what "sluggish" felt like.

content-visibility: auto on the grid's cards is the browser's own answer: off-screen
cards skip layout, paint and compositing and come back as they scroll near the
viewport. The grid's tracks are sized by minmax(180px, 1fr) rather than by card
content, so skipping that content cannot move the columns; contain-intrinsic-size
supplies the block-axis guess and `auto` remembers each card's real size after its
first render, so scroll height and offsetTop - which BrowseView's keep-the-selection-
on-screen effect reads - stay honest. Not behind ?pi=1: there is no visual difference
to trade away.

SHOW_CARD_BLUR separates the repeated frosted surfaces (every card, every list row)
from the handful of panels wrapped around them, because the two behave nothing alike
and lumping them together is what made the first Pi profile five times slower. A panel
is one live backdrop copy that buys its whole subtree a compositing layer; a card is
one of three hundred sitting directly over the animated canvas. ?pi=1 now drops the
card blur and keeps the panel blur.

2514ecbc35 Measure the Pi profile on the Pi, and keep only what helped 
The first cut of ?pi=1 switched off the two things that look most expensive - the
backdrop-filter glass blur and the decorative CSS animation loops - and made the device
slower, not faster: 53.5% of a core idle became 118%. Measured on musicdolphin, sum of
the Firefox process tree, idle on the browse screen, 15s average:

  full app                                       53.5%
  + ambient canvas at half resolution            25.0%   <- the whole win
  + 30fps cap on top of that                     25.0%   (no idle change)
  + decorative CSS animation loops off           24.6%   (noise; left on)
  + backdrop-filter glass blur off              118.1%   <- 5x worse

The blur is what promotes each glass panel to its own compositing layer. Without it the
animated canvas and the whole album grid above it collapse into one layer and every
canvas frame repaints all of it. The most expensive-looking CSS in the app is what was
keeping the rest of it cheap. SHOW_GLASS_BLUR and SHOW_DECORATIVE_ANIMATIONS therefore
go back to unconditionally on, in both the music app and the typing game, with the
numbers written down next to them so the next person does not repeat this.

What is left is one real change - paint a quarter of the pixels - plus three caps that
only bite while something is playing and so are not in the table above: 30fps on the
canvas, 60 bubbles alive at once, and ten progress-bar re-renders a second. Those three
are unmeasured; measuring them means playing audio.

cc3db44c4e Add a ?pi=1 profile, and stop re-deriving search keys per keystroke 
Two separate costs, both measured on musicdolphin (Pi 4, 1920x1080 kiosk), where the
app was burning ~70% of a core with nothing happening on screen.

Per-frame work. The ambient canvas repaints a full-screen gradient plus a particle
field every frame, and `usePlaybackClock` pushes a React setState per animation frame
into both PlayView and PlayerBar for the whole length of a track. `?pi=1` (lib/
lowPower.ts) makes those cheaper rather than switching them off: the canvas paints a
quarter of the pixels at 30fps with a bubble cap, and the clock renders ten times a
second - a progress bar advances one pixel every few hundred ms and its label has
one-second resolution, so nothing on screen can tell. Only the effects with no cheap
version actually go: the backdrop-filter glass blur and the decorative CSS loops.
Also drops a redundant full-canvas clearRect that the opaque gradient always covered.

Search. normalize() runs a Unicode NFD decomposition, and albumMatches/songMatches
called it on every album title and every track title on every keystroke - 4969 of them
for a track search, whose answer cannot change until the library does. buildSearchIndex
does it once per library payload; a keystroke is now String.includes over strings that
already exist. On the real library that is 33ms -> 3.4ms for an eight-letter track
query on a laptop, and this runs on a Pi. The same index partitions albums by shelf and
pre-sorts each shelf's categories, which App and BrowseView were deriving separately
from the same data.

a7fb56c9fe Target the Python that Raspberry Pi OS ships 
Requiring 3.13 meant the device needed an interpreter the distribution does not
have, which is what dragged uv in, and uv then had to be matched to the Pi's
32-bit userland by hand and to build Pillow from source because no armv7 wheel
exists for a 3.13 ABI. Dropping to 3.11 removes all of that: apt provides the
interpreter and piwheels has prebuilt armhf wheels for the native dependencies.

The 3.13-only syntax was shallow - PEP 695 throughout, which converts back
mechanically:

  type X = Y               ->  X: TypeAlias = Y
  type Handler[E: Event]   ->  E = TypeVar("E", bound=Event) plus a plain alias,
                               which is generic anyway because it carries a TypeVar
  def f[T: Bound](...)     ->  a module-level TypeVar

Also drop the one @override (3.12, and static-only), and stop the lirc test
harness calling Server.close_clients(), which is 3.13: the scripted handler now
releases its connection when asked, which is what that call was there to force.

Verified on 3.11.14 - 485 passed, mypy strict clean - and still 496 passed on
the 3.14 dev venv, which additionally has the analysis extra.

fa3d92189c Keep only the newest 50 episodes of each podcast 
A show that has published for years is unbounded: GEOlino Spezial alone is 358
episodes and 5.8 GB, and the device it syncs onto is a 30 GB SD card that also
holds the rest of the library. Nothing stopped the 6-hourly poll from eventually
filling it.

Cap each show's folder at general.podcast_episode_limit (default 50, null to
keep everything), pruning the oldest past that after each sync pass.

The same limit caps what is downloaded, and it has to be one number for both.
Prune to the newest N but keep fetching everything the feed offers, and every
poll would re-download exactly the episodes the previous one deleted - forever,
at full size, since missing_episodes() decides purely from what is on disk.
There is a test for that specific loop.

Pruning only touches files named the way this module names them
(YYYYMMDD - Title.ext), so feed.txt, folder.jpg, the failed-download record and
anything placed by hand are all left alone; a parse that fails means "not ours",
not "delete it". An episode's sidecar cover goes with it. A pass that only
deleted still reports a change, because the library needs the rescan just as
much as it does after a download.

dd14f5d901 Add a script to seed a device's library and analysis cache 
Copying the library to a Pi is one rsync; copying the cache with it is not,
because its three parts travel differently. covers/ is keyed by the album
folder's path relative to the library root, so it survives the move. analysis/
is keyed by name:size:mtime, so it survives only if mtimes do - hence -a
everywhere, and a comment saying why. index.json holds absolute source paths and
must not be copied at all: scan_library() reuses a cached album on a matching
(name, size, mtime) fingerprint without re-checking the path, so copying it
leaves every album pointing at the dev machine and playback fails on files that
are present. It is the cheap part, and the device rebuilds it on first scan
while reusing everything expensive.

Syncs shelf by shelf rather than the whole directory, which is what makes
--delete safe: config.yml, tippen-curriculum.yml, tippen-progress.json and the
cache all live in the same directory on the device and have no counterpart here.
Preflight checks ssh, sizes the transfer and refuses to fill the SD card.

274085b92e Stop tracking the library cache 
python-backend/.gitignore lists /.musicmouse-cache, but index.json and seven
cover JPGs were committed before that ignore existed, so the ignore never
applied to them. index.json is a 2 MB machine-specific blob holding 6606
absolute /home/martin/... paths, rewritten on every app start - it showed up as
modified in git status permanently, and a deploy checkout would have shipped a
dev machine's index to the device.

The files stay on disk; only the tracking goes.

f3337975c2 Celebrate a media unlock with a treasure chest that opens 
The reward pipeline worked end to end already, but it had nothing to show for
itself: the unlock was one more line at the bottom of the result sheet, a 52px
thumbnail with the generic 520ms pop, below the stars, the stats, the progress
bar, the animal ladder and three other badges. The sound was `playFanfare`, the
same chirp used for a new lesson and a new aquarium pet. It fired correctly and
was impossible to notice.

This is the only reward that reaches outside the game, so it now gets the whole
screen. A chest drops in shut and rattles, the lid swings open on a burst of
light and confetti, the cover art rises out of it, and the tune is a real melody
- two seconds landing on a held major chord - rather than another blip. It is
dismissed by hand, so she can look at what she won for as long as she likes.

On the map, the 15px 🎁 becomes a drawn chest, shut while the reward is unwon
and open with the cover inside once it has been. It is rendered as a sibling of
the lesson node rather than a child, because a locked node is dimmed to 45% and
the chest that most needs to be bright is the one three worlds away.

One real bug behind the missing badge state: `progressFromApi` dropped the
`earned` flag the backend already sends, so the map could not tell a claimed
reward from an unclaimed one. Added, with a test that names it - a hand-written
field mapping loses fields without failing a type check.

e6f6b15cc7 Make the lesson map the floor screen of the typing tab 
The aquarium was a separate landing screen in front of the map, showing the pets
collected so far and a "Weiter üben" button. But the pets already swim behind
every screen in the tab, so the screen mostly restated what was visible anyway,
at the cost of one extra step between opening the tab and typing.

The map absorbs what was worth keeping: the "Weiter üben" button now floats over
it, and the pets, streak and best animal move into the header. One Escape from
the map leaves the tab entirely, where it used to go back a screen first.

f3f7082fb8 Draw locked covers as artwork instead of a question mark 
A reward-gated album showed a bare ❓ over the generated gradient, which reads as
"something is broken" rather than "something is waiting". It is now a proper
placeholder cover, with a separate one for audiobooks and podcasts.

36e93be79b Let a lesson list review keys beside the two it introduces 
A lesson's `keys` was capped at two outright, which made it impossible to write
"K, with the four keys before it still in play". The cap now counts only what is
*new*; keys already taught can be listed freely, and the spotlight falls on the
new ones alone, so a lesson titled "K" drills K instead of spreading itself
evenly over all five keys it names. A round that introduces nothing new still
spotlights its whole list - that is the "mixed" replay, unchanged.

Also documents `unlocks:` paths as relative to the library root. Absolute and
"~" paths still resolve, so an existing file keeps working, but a relative path
survives moving the library.

b6342cc117 Drop the pearls currency 
Pearls were earned every run and spent on nothing: the aquarium fills up by
finishing worlds, not by paying for it. A counter that only ever goes up is one
more stat competing for attention on the result sheet and the home screen, and
one more field to carry through the run payload, the progress file and both test
suites.

Stars and the animal ladder already say how a run went, so nothing is lost.

fd6283718c Analyse tracks in a pool of worker processes 
A first pass over an unanalysed library is hours of librosa, and there was no
reason for a desktop to spend them one core at a time. Analysis now runs in a
process pool sized by `general.library.analysis_workers`, defaulting to one per
core bar one (capped at 8) when the key is absent.

Two consequences worth knowing before touching this: whatever an `Analyzer`
returns has to be picklable, and an analyzer that keeps state on its own
instance - a test double counting calls - only behaves as written with
`analysis_workers=1`.

modes; with jellyfish gone, bubbles is now always used instead of the
two alternating - no lessons need to be dropped.

a69db98241 Use a plain text note glyph for the music tab, not the emoji 
Setting color explicitly wasn't enough: the 🎵 emoji has its own
baked-in colour (a muted grey-blue on at least one real platform) and
simply ignores the CSS color property, unlike a plain Unicode symbol.
Swapped to the bare eighth-note character (♪), which renders as text
and finally responds to the color already set on the button.

e243862769 Fix barely-visible music-note tab icon 
The glass-bar redesign dropped the explicit icon color, so inactive
icons fell back to the browser's default text color - fine for icons
that render as full-color emoji, but the music note apparently renders
as a plain glyph on at least one platform, making it nearly invisible
against the bar's near-white glass background. Set it explicitly.

b8f9f6d537 Give the tab rail its own glass bar and reserve space for it 
The three tab buttons now share one frosted glass pill instead of each
floating separately, and BrowseView/RoomView reserve TAB_RAIL_CLEARANCE
of right-side padding so a full-width row or grid never renders under
it - verified against the real library, where dense rows (e.g. Conni's
82 audiobooks) previously butted right up against the rail.

Also gitignore the real (non-.example) tippen-curriculum.yml and
tippen-progress.json, matching config.yml's own privacy treatment,
since the curriculum now contains real reward paths into a personal
library.

57ead93497 Apply lock state to category-tile cover previews too 
Verified the whole reward-lock feature against a real library with an
actual browser (Playwright + headless Chromium): the album-grid cards
already showed the question-mark placeholder for a locked album, but
its 2x2 preview thumbnail in the category-tile view (the screen before
drilling into an artist/category) still rendered the real cover art,
since that Cover call never received the locked prop.

7f5e2733c2 Merge the typing game into the music player as a tab, with lock/unlock UI 
Moves tippen from a standalone app into web/ as a third tab (audio player /
smarthome / typing), replacing the old single room-toggle corner button with a
vertical icon tab rail. Curriculum and progress now come from the backend
(musicmouse/tippen/*) instead of a build-time YAML import and localStorage.

Adds reward-driven lock rendering: Cover/BrowseView/AlbumModal show a question
mark for locked albums/tracks with a hint on what unlocks them, and
ResultSheet gets a new unlock-animation block alongside the existing
lesson-unlock and aquarium-creature celebrations.

CSS from the two apps is merged carefully: identical rules (bubble/card/
key-cap/view-enter/backdrop-enter and their keyframes) are shared as-is,
while rules that bake in each app's own hue are kept separate under a
`tp-` prefix and scoped to the typing tab's own .tp-stage wrapper, so
neither app's look bleeds into the other's.

f7a5d24d8d Add backend support for the typing game: curriculum, progress, and reward unlocks 
Moves the typing app's lesson plan and progress from client-side YAML/localStorage
into the backend, and adds a reward system that ties passing a lesson to unlocking
part of the music library. Lock state is always recomputed live from curriculum x
progress x the live library, never persisted separately.

df89acd9a8 Fix podcast episode downloads: ffmpeg muxer bug and dead-URL retry storm 
_extract_audio wrote transcoded audio to a .tmp temp path, so ffmpeg
couldn't guess a muxer from the filename and aborted on every video
episode whose source was still reachable. Pass -f mp3 explicitly instead
of relying on the extension.

Separately, a permanently 404'd episode was retried on every startup and
every 6-hour poll forever, since nothing remembered past failures. Track
failed downloads per show folder with a 7-day backoff before retrying.

829ea89386 Fix search: allow spaces and match multi-word queries as separate words 
Space was hard-coded as the global play/pause toggle, so it never reached
the search-typing logic - typing "geolino azte" would toggle playback
instead of adding the space. Now a space is appended to an in-progress
search instead.

Search also required the whole query to be one contiguous substring of
title + artist, which misses queries like "conni rad" for "Conni lernt
Rad fahren" or "geolino azte" for a podcast episode titled "Azteken" by
"GEOlino Spezial" (title comes before artist). Each word is now matched
independently, in any order.

a3b2c0ce2f Add a vim-style keyboard layer: Ctrl navigates, Shift controls transport 
Ctrl+h/j/k/l move the highlight in whatever list is on screen - the browse
grid, search results, or an open album's track list - the same job the
arrow keys already do, just reachable without leaving the home row.
Ctrl+d/u add vim's own half-page jump. Shift+h/j/k/l/m are transport
(previous/next, volume, mute) from anywhere, including the room page,
matching the muscle memory of other vim-ish media apps; every other
Shift+letter still reaches search untouched; only the shifted letter
form of those five keys is intercepted.

Shift+Enter opens an album's track list (the keyboard equivalent of
clicking its cover, which had no key of its own until now) instead of
playing it outright; Ctrl+j/k then move a visible highlight through that
list, and Enter plays whichever track is highlighted. Falls back to plain
ENTER's behaviour for a category tile or a podcast episode, neither of
which has a track list to show.

Mute (Shift+M) is new - nothing was bound to it before.

ba7f082f48 Rework navigation for a consistent music/room toggle and back button 
- Replace the "Mein Zimmer"/"Musik" text pills and the help button with
  two fixed circular corner buttons: a music/room toggle (top-right)
  and a single "back one level" button (top-left) used everywhere -
  search, categories, and the play view.
- Split `view` (browse/play) from a new `page` (music/room) in UiState
  so toggling to the room and back leaves the music side - search,
  selection, even the full-screen play view - exactly as it was.
- Back peels one step at a time (search, then track-search mode, then
  group+category together, since a root shelf tile sets both at once
  and undoing that jump should be one step too).
- Album cards: click the cover to open the track list, click the title
  to start playing immediately (matching what Enter already did from
  the keyboard). Audiobook cards drop the artist line and clamp the
  title to a fixed height so covers stay aligned across a row.
- Root shelf group headings ("Musik", "Hörbücher", "Podcasts") are now
  the link into that group's full category grid, replacing the
  separate search-icon button.
- "Taste zuweisen" is now an icon-only round button, moved to the
  bottom-right so it doesn't sit under the new toggle.

69119bb72a Add per-episode podcast cover art and fix nested album grouping 
- podcast_feeds.py: fetch per-episode cover art from a feed's itunes:image
  (when it's genuinely distinct from the channel image) or, failing that,
  from the og:image on the episode's own linked page; extract audio from
  video-only enclosures via ffmpeg; match podcast-dl's filename convention
  (illegal characters become "_" instead of being dropped) so enabling
  feed.txt on an already-downloaded show doesn't re-download its back catalog
- scanner.py: _cover_for_episode now checks for a same-stem sidecar cover
  image before falling back to embedded ID3 art and the shared folder cover
- scanner.py/__init__.py: fixed a bug where an album folder nested one level
  deeper than usual (an age-range grouping folder, say) was mistaken for an
  empty album and skipped; added periodic progress logging for long scans
  and analysis passes

Adds a TCP client for lircd's classic protocol: play/pause/next/prev/
volume/mute map to the same intents every other front-end already
emits, and number keys 0-9 play an assigned album/audiobook from the
start or a podcast show's newest episode, resolved fresh on every
press. The mapping is configured in config.yml and editable from the
frontend: a small "Taste zuweisen" button on the play screen (or the
A+digit keyboard shortcut) opens a 10-key picker to assign whatever is
currently playing.

A show folder under Kinderpodcasts/ opts in by containing a feed.txt marker
naming its RSS feed. A new PodcastFeedService polls every such feed every 6
hours (and once at startup), downloads any episode not already on disk using
the existing YYYYMMDD - Title.ext convention, and triggers the same
rescan-and-broadcast sequence "Bibliothek neu einlesen" already uses - now
shared via App.rescan_library() instead of duplicated. A show with no
feed.txt is untouched, so there is no new config section for this.

2e0e6ad199 Add librosa beat/mood analysis and an Ambience background driven by it 
The background worker now runs a real librosa analyzer (tempo, beat grid,
per-second energy/valence curves) instead of only the null baseline, kept
behind build_analyzer() so a plain checkout without the analysis extra still
runs fine. The web player reads that per-track analysis and drives a new
animated "Ambience" background (bubbles, colour, current) that reacts to the
beat and the mood curve as the track plays, plus a debug overlay for tuning
it. Also adds a one-off script to backfill podcast cover art from iTunes.

a8ed350aec Add "Mein Zimmer" room-control page (Home Assistant, proxied through the backend) 
Implements the room-control page from the design mockup: a scenes row above cards
for shutters, color lamps, and brightness-only lamps, all driven by a new
`general.ha` config section (server URL, token, ordered device/scene lists).

The backend proxies every Home Assistant call server-side (GET/POST /api/ha/...)
rather than the browser calling Home Assistant directly, so the long-lived token
never leaves the LAN device and Home Assistant's own CORS settings don't need to
know about musicmouse at all. Card kind (shutter/color/brightness-only) is
inferred at runtime from what Home Assistant reports about each entity, not
configured explicitly.

Also stops tracking python-backend/config.yml, which had drifted into the repo
despite its own header saying it shouldn't be - it now carries real credentials
locally and needs to stay untracked.

/* BEGIN USAGE */
/**
* <three-d-stage> — 3D object viewer + exporter shell (three.js).
*
* The stage owns the whole scene: WebGL renderer, neutral studio lighting
* with a soft ground shadow, orbit controls (drag to orbit, wheel to zoom,
* right-drag to pan), a camera auto-framed to the object's bounds, resize
* handling, and a download toolbar that exports the current object as
* OBJ + MTL or GLB (binary glTF). FBX cannot be exported in the browser;
* GLB is the interchange format every modern 3D tool imports.
*
* three.js loads through the page's import map. Include this EXACT pinned
* map in <head>, before any module runs — versions and integrity hashes
* stay together (same map the "3D object" skill mandates):
*
* <script type="importmap">

* <script type="module">

* // …build the model out of named meshes with named materials —
* // the names become the o / usemtl entries in the exported OBJ…
* stage.setObject(model);
* </script>
*
* Attributes:
* name — export file basename (default "model")
* background — CSS color behind the scene (default a warm paper tone)
* autorotate — when present, a slow turntable until the user interacts
*
* Model in real-world meters, centered on the origin, y-up — exports
* inherit the scene's units and orientation. The stage fills its own box;
* size it with ordinary CSS (default 100vw/100vh page hero).
*
* Default setup: neutral studio lighting (hemisphere + key + fill), a
* soft ground shadow, and NO environment map — so high metalness has
* nothing to reflect and renders near-black. Cap metalness around
* 0.3–0.4 and carry a metal look with a brighter base color. The copied
* file is yours: adjust the lights, shadow, or background in _boot()
* when the object needs a different look.

# MusicMouse — repo overview
Orientation doc for AI agents (or humans) working on this repo for the first time.
## What this is
MusicMouse is a DIY, Toniebox-style physical music player for kids, shaped like a mouse
and living on a shelf. Small 3D-printed animal figurines (fox, owl, dog, elephant,
squirrel, crocodile, rabbit, snowman, puppy — see `hardware/3dprints/figures/`) each
carry an RFID tag. Placing a figurine on the mouse starts that figure's playlist. The
mouse also has a rotary encoder and capacitive touch areas (ears/feet) for
volume/skip control, addressable RGBW LED rings with animated effects, and MQTT/Home
Assistant integration.
## Repo layout
| Path | What it is |
|---|---|
| `python-backend/` | Python host application — the main runtime. Has its own `README.md` with the architecture; start there for backend work. |
| `web/` | React + TypeScript front-end (Vite). Browse the whole library and play any of it from a browser. Built output is served by `python-backend` itself. |
| `esp-firmware/` | ESP32 firmware (C++, Arduino framework via PlatformIO). Reads the RFID reader and buttons, drives the LED strips, talks to `python-backend` over serial. |
| `hardware/` | 3D-print models for the figurines and enclosure (FreeCAD/Blender/OBJ/STL), a Fritzing electronics sketch, datasheets, and `pinout.md` (RFID reader + button-board wiring). |
| `claude-design/` | The interaction and visual spec the web front-end was built from ("Dolphin Beats"), as a standalone HTML mockup with hardcoded data. `web/` is the real implementation; the mockup is kept as the reference for the keyboard model and the styling. It also contains a second page, "Mein Zimmer" (room lights), which is **not** implemented. |
## How the pieces talk to each other
- **ESP32 firmware ↔ `python-backend`**: a length-prefixed binary protocol over serial.
Frames are `uint32 magic | uint8 type | uint16 size | payload`, little-endian, with
firmware log text interleaved on the same link. The Python side lives in
`python-backend/musicmouse/devices/wire.py`, the firmware side in
`esp-firmware/src/Messages.h`.
The contract is hand-duplicated in two languages. `tests/test_wire.py` parses
`Messages.h` and fails if the message ids drift, and `tests/test_effects.py` pins the
exact bytes of every effect payload — so a firmware change that breaks the host now
breaks a test instead of just the LEDs.
- **`python-backend` ↔ `web/`**: JSON over HTTP for the library and for commands, plus a
push-only websocket at `/api/ws` for state. Commands emit exactly the same *intents*
the physical buttons emit, so the web UI has no privileged path — and no way to get
out of step with a figure someone puts on the reader. See
`python-backend/README.md` for the endpoint list.
- **`python-backend` ↔ Home Assistant**: MQTT only. The backend publishes three
discoverable lights, a player sensor, a volume number, transport buttons, device
triggers for every button and touch area, and a tag scanner for the RFID reader. It
does *not* call Home Assistant services directly any more; behaviour like "the left
ear turns the room light pink" is an HA automation. See `python-backend/README.md`
for the trigger topics and the old colour mapping.
## Running it
```sh
python -m musicmouse --config /media/musicmouse/config.yml
```
On a machine with no mouse attached — real audio and a real web UI, no serial port:
```sh
python -m musicmouse --config ./config.yml --no-hardware
```
`general.serial_port: simulate` does the same thing from the config, and
`general.alsa_device: simulate` swaps in a silent player. Both warn at startup, and
both keys are required - omitting one is an error rather than an implicit simulation.
Or with no hardware *and* no audio:
```sh
python -m musicmouse --config ./config.yml --simulate
```
The simulator runs the whole app against a fake serial link and a fake player, either
interactively or from a scenario file. `python-backend/musicmouse.service` is the
systemd unit for the device.
For front-end work, run the backend (either way above) and then:
```sh
cd web && npm install && npm run dev # http://localhost:5173, /api proxied to :8080
```
`npm run build` writes `web/dist`, which `general.web.static_dir` points at in
production so one process serves both the UI and the API.
## Config
`python-backend/config.yml.example` documents the schema. In short:
- `general.{library.*, serial_port, baudrate, reconnect_interval, alsa_device,
min_volume, max_volume, initial_volume, volume_increment, button_leds_brightness,
audio_extensions, mqtt.*, web.*}`
- `figures.<name>.{id, colors}` — `id` is a 5-byte hex RFID tag, unique per figure;
`colors` is exactly four (`primary, secondary, bg, accent`), each `"#rrggbb"` or
`"wNN"`.
`general.library.root` is the one path to the music. The shelves under it are fixed
names, not settings, because each has quirks the scanner knows about:
```
<root>/Figuren/<figure name>/ one folder per figurine
<root>/Musik/<Artist> - <Album>/ albums, grouped by artist
<root>/Hörbücher/<Artist> - <Album>/ audiobooks, grouped by character
<root>/Kinderpodcasts/<Show>/ shows, newest episode first
```
Config is validated with pydantic: unknown keys are errors, and every problem is
reported at once.
## Notes for agents
- The backend has `pytest`, `ruff` and `mypy --strict` configured in
`python-backend/pyproject.toml`, and no CI. Run all three before proposing changes.
- Prefer adding a scenario in `python-backend/scenarios/` over a hand-rolled test when
the behaviour is end-to-end — those files are executed by the test suite.
- `python-backend/notebooks/` is university course material on chord recognition, not
part of the app.
- The firmware has no automated tests beyond a PlatformIO `native` env for LED effects.
- The front-end has `vitest` over the pure modules (`web/src/lib/`) and `tsc --noEmit`;
there is no component-level test harness. `npm run test` and `npx tsc --noEmit` are
the two checks.
- The library index is cached under `general.library.cache`. It is keyed by file mtime
and size, so **a change to how the scanner derives a title, artist or series is
invisible until the cache is invalidated** — bump `_INDEX_VERSION` in
`musicmouse/library/cache.py` when you touch that logic.
- Track analysis (librosa) runs in a pool of worker *processes* - see
`musicmouse/library/workers.py`. Anything an `Analyzer` returns therefore has to be
picklable, and an analyzer that records state in its own instance (a test double
counting calls) only behaves as written with `analysis_workers=1`.

Firmware Planning
-----------------
- input commands:
- led: effect + parameters
- off
- single color
- multiple color HSV fade, list of colors with timings
- circular motion (already exists)
- chained events? e.g. circle two times then fade
- effects:
- welle fuer an und aus
- breathe waehrend an, oder farbgradient
-
- output infos:
- nfc read: with id
- nfc remove
- button presses, (possible also long press, double click, etc)
- rotary encoder up down + current numeric state
- on led effect end?
TODO
----
1) case redesign
- slightly smaller led ring (10mm -> 9mm) [ok]
- thicker top of inner ring, but cutouts for reader [ok]
- adjust reader stands position [ok]
- bottom for led ring snap-in [ok]
- bottom for inner ring [ok]
- stands for own "pcb" [ok]
- 2 cutouts for cables [ok]
- checks, compared to existing print
- same diameter, very slightly smaller
- larger overlap of LED ring
- minimal wall thickness for led ring top and side
- check total height - compare to existing

# MusicMouse backend
The host application: it reads RFID tags, buttons and touch areas from the ESP32
firmware over serial, plays music through VLC, drives three LED strips, indexes the
music collection, and exposes everything to Home Assistant over MQTT and to a browser
over HTTP.
```
ESP32 ⇄ MusicMouseDevice ─┐ ┌─► MqttService (state out, intents in)
VLC ⇄ VlcPlayer ────────┼──► EventBus ──────────►┤
broker ⇄ MqttService ──────┤ ▲ └─► WebService (state out, intents in)
browser ⇄ WebService ───────┘ │
reactions/*.py ── call actions on ──► device / player
```
Three objects own the outside world, one bus carries everything, and the *reactions*
are the only place that decides what should happen. Adding a new way to control the
mouse means adding a service that emits the same intents - no device or reaction
changes. The web front-end was added exactly that way.
## Running it
```sh
pip install -e '.[dev]'
python -m musicmouse --config /media/musicmouse/config.yml
```
See `config.yml.example` for the schema and `musicmouse.service` for the systemd unit.
Config problems are reported all at once with the path to each one; unknown keys are
errors, not silent no-ops.
### On a host with no mouse attached
The web front-end is a complete way to drive the player, so the backend is useful on a
machine with no serial port and no sound card worth grabbing. Two config keys say so,
each by taking the literal value `simulate`:
| Setting | `simulate` gives you | Warned about as |
|---|---|---|
| `serial_port` | no serial link; RFID, buttons and LEDs are inert | "running without the mouse" |
| `alsa_device` | the simulator's player: everything works, nothing is audible | "nothing will be audible" |
Both keys are **required**. Leaving one out is a config error, not a shortcut to
simulation - running blind or silent has to be asked for, so a config that lost a line
fails loudly instead of booting into something that looks like it is working. The
warnings are repeated on every boot for the same reason.
`--no-hardware` forces the serial half regardless of the config, for a one-off run:
```sh
python -m musicmouse --config ./config.yml --no-hardware
```
Note that `alsa_device` has no "just use whatever" value. VLC's own default would seize
whatever the desktop is playing through, which is the wrong thing to do silently - name
a device (`"default"` is the system one) when the machine is meant to make noise.
### Without hardware
The simulator runs the entire app - real bus, real device, real reactions, real MQTT
if configured - against a fake serial link and a fake player.
```sh
python -m musicmouse --config ./config.yml --simulate
```
```
musicmouse> place fuchs
in RfidTokenRead(04a1b2c3d4, figure='fuchs')
rfid fuchs
led ring: SwipeAndChange(AlexaSwipe(#(1.0, 0.4, 0.0, 0) -> ...))
play playing
musicmouse> press right
play track 1: 01 - Song 1
```
`help` lists the verbs. The same verbs go in a scenario file:
```sh
python -m musicmouse --config ./config.yml --simulate --script scenarios/smoke.txt
```
Scenario files run on a virtual clock under pytest, so `wait 1s` costs microseconds and
every file in `scenarios/` is part of the test suite. A session reproduced by hand at
the prompt becomes a regression test by pasting it into a `.txt` file.
## Layout
| Path | What it is |
|---|---|
| `musicmouse/bus.py` | One FIFO queue on one loop. Thread-safe `emit()` - which is how libVLC's callback thread stops reaching the serial transport. |
| `musicmouse/events.py` | The vocabulary: **input** (something happened), **intent** (something was requested), **state** (something changed). |
| `musicmouse/devices/` | `mouse.py` (firmware), `player.py` (VLC), `wire.py` (pure codec), `serial_link.py` (transport + reconnect). |
| `musicmouse/reactions/` | The policy. `@on(SomeEvent)` functions that get the app and act. |
| `musicmouse/library/` | The music collection: scanning, tags, cover art and its colours, the cache, and the seams for future track analysis. |
| `musicmouse/services/mqtt/` | Home Assistant entities: three lights, a player sensor, a volume number, transport buttons, device triggers, a tag scanner. |
| `musicmouse/services/web/` | The browser front-end's API: the library, a state websocket, command endpoints, and parent-mode settings. |
| `musicmouse/simulator/` | Fake transport and player, the driver vocabulary, the REPL and the script runner. |
| `musicmouse/config.py` | Pydantic schema, validation, and human-readable error formatting. |
## Checks
```sh
pytest # unit + scenario tests
ruff check .
mypy # --strict, configured in pyproject.toml
```
`tests/test_wire.py` parses `../esp-firmware/src/Messages.h` and fails if the Python
message ids drift from the firmware's - the contract is hand-duplicated in two
languages, and it had already drifted once (`BUTTON_EVENT` was missing on the Python
side). `tests/test_effects.py` pins the exact bytes of every effect payload.
## LED arbitration
`MusicMouseDevice` is the single writer to each zone, and the most recent effect wins -
whether it came from a figure animation or from Home Assistant. There is no priority
scheme. Every write emits `LedEffectChanged`, and the MQTT light entities publish their
state from that rather than echoing their own commands, so HA keeps showing the strip's
real state when a figure animation overrides a colour it set.
## Home Assistant
The backend no longer calls Home Assistant directly (`hass-client` is gone). It
publishes what happened; the automations live in HA.
MQTT device triggers are published for every button (`pressed`, `double_clicked`,
`long_pressed`), every touch area (touched/released), and the RFID reader appears as a
tag scanner. Topics are under `musicmouse/trigger/…` and `musicmouse/tag`.
### Recreating the old room-light behaviour
Two behaviours used to be hard-coded in `main.py` and now need automations:
**Rotary press toggled the room light.** Trigger on the `rotary_pressed` device
trigger, action `light.toggle` on `light.kinderzimmer_fluter`.
**Touching a body part set a colour** on `light.kinderzimmer_fluter` and
`light.music_mouse_regal_licht`:
| Touch area | Old service data |
|---|---|
| `right_foot` | `rgb_color: [235, 255, 67]` |
| `left_foot` | `color_temp: 469` |
| `right_ear` | `rgb_color: [101, 49, 255]` |
| `left_ear` | `rgb_color: [255, 74, 254]` |
Trigger on the corresponding `*_touched` device trigger and call `light.turn_on` with
that data.
## The library
`general.library.root` is the one path to the music. The shelves under it are fixed
names rather than settings (`musicmouse/library/sections.py`), because each has quirks
the scanner has to know about:
| Folder | Shown as | Why it is special |
|---|---|---|
| `Figuren/<figure>/` | an album per figurine | the folder name *is* the figure name from the config |
| `Musik/<Artist> - <Album>/` | music, grouped by artist | plain ID3 |
| `Hörbücher/<Artist> - <Album>/` | audiobooks, grouped by character | `album_artist` is a credit list; only the name before the first comma groups usefully |
| `Kinderpodcasts/<Show>/` | audiobooks, newest episode first | the tags are useless here - `artist` is the presenter list and `album` is the feed name, so the *folder* is the show |
Only files whose suffix is in `audio_extensions` are read, and dotfiles are skipped, so
a podcast downloader's `archive.json` and its half-finished `.download.tmp` never reach
a playlist.
Drop a `feed.txt` into a show folder (its first line the show's RSS feed URL) and the
backend becomes that podcast downloader itself: every six hours it checks the feed and
saves any episode not already on disk, named `YYYYMMDD - Title.ext` like a hand-placed
one so it sorts and scans identically. A show with no `feed.txt` is untouched, exactly
as before - the file is the opt-in, there is no separate setting for it.
Each album carries three colours, pulled out of its cover art with Pillow (or
synthesised from a hash of its id when it has none). The frontend paints cards with
them and the LED strips run the first of them, so shelf and screen agree.
### The cache
`general.library.cache` is a directory, not a file, because its contents cost wildly
different amounts to produce:
```
index.json cheap: tags and structure. Rebuilt freely.
covers/<album_id>.jpg medium: art extracted from an ID3 APIC frame
analysis/<track_key>.json expensive: reserved for offline audio analysis
```
Deleting the whole directory is safe; deleting it throws away analysis that is minutes
of DSP per track, which is why anything expensive is keyed by *file content* rather than
by album id - renaming a folder or re-sorting a section then costs nothing.
An entry is reused whenever its files' sizes and mtimes are unchanged. That means a
change to how the scanner derives a title, artist or series is invisible until the cache
is invalidated: bump `_INDEX_VERSION` in `musicmouse/library/cache.py` when you touch
that logic.
**Track analysis is not implemented.** `musicmouse/library/analysis.py` fixes the shape
of the results - scalars (`tempo`, `energy`, `valence`, `brightness`) travel inline with
the index, and a beat grid lives in its own file and is fetched per track - so an
analyzer can be added later without touching the scanner, the API or the frontend. It
will go behind an optional dependency group, and because results are content-keyed
files, they can equally well be computed on a workstation and the `analysis/` folder
copied to the device.
## The web front-end
`web/` in the repo root, served by this backend when `general.web.static_dir` is set.
| Route | Purpose |
|---|---|
| `GET /api/library` | Every album with its tracks and colours. ~90 kB, sent once. |
| `GET /api/albums/{id}/cover` | The cover, or 404 - the client paints the album's colours instead. |
| `POST /api/library/refresh` | Rescan in the background; connected clients are told when it lands. |
| `GET /api/state` | Snapshot: what is playing, where, how loud. |
| `WS /api/ws` | Push only. A snapshot on connect, then a frame per change, plus the position at 2 Hz while playing. |
| `POST /api/play` | `{album_id, track_index?}` |
| `POST /api/resume` `/pause` `/next` `/previous` `/seek` | transport |
| `POST /api/volume` | `{percent}` or `{delta_percent}` |
| `GET` `PUT /api/settings` | parent mode |
Two decisions worth knowing:
**Search is not an endpoint.** The whole index goes to the browser and filtering happens
there, which is what makes the design's type-to-search feel instant.
**Volume is a percentage at this boundary.** `max_volume` is a parent's business, not a
child's, so it never crosses into the browser: `100 %` means whatever ceiling is
configured, and the mapping lives in `services/web/settings.py` so MQTT, the rotary
encoder and the firmware carry on in device units.
### Parent mode
`?parentMode=1` reveals a settings panel for the volume limits, the rotary step and the
button brightness. Saving writes `config.yml` back through ruamel's round-trip loader,
so the file keeps its comments, and a new ceiling applies to the running player rather
than waiting for a restart.
This **hides** the settings; it does not protect them. There is no authentication on any
endpoint, which matches a device on a home network - put it behind a reverse proxy if
that is not good enough.

# settings, because each one has its own quirks the code already knows about:
#
# <root>/Figuren/<figure name>/ one folder per figurine
# <root>/Musik/<Artist> - <Album>/ albums, grouped by artist
# <root>/Hörbücher/<Artist> - <Album>/ audiobooks, grouped by character
# <root>/Kinderpodcasts/<Show>/ shows, newest episode first
#
# A cover.jpg next to the audio is used if present, otherwise the art is pulled out
# of the files' tags. Relative paths resolve against this file's directory.
library:
root: /home/martin/Music
# Scan results, extracted cover art and track analysis. Safe to delete: the index
# is rebuilt on the next start. Deleting it does throw away track analysis, which
# is expensive to recompute.
cache: .musicmouse-cache
# How many tracks the background analyzer may work on at once, each in its own
# worker process. Omitted means one per core bar one (capped at 8), which is what
# turns a first-time pass over a whole library from an overnight job into a coffee
# break on a desktop. Set it to 1 on a machine that has better things to do, or to
# a specific number to cap how much of it analysis may take.
# analysis_workers: 4
# Serial port the ESP32 firmware is on. A dropped link is retried, not fatal.
# Required - use "simulate" to run without the mouse attached, which is a complete
# setup on its own because the web front-end can drive the player by itself. RFID,
# buttons and LEDs then do nothing, and startup says so every boot.

# is handy when working on the web UI on a machine whose audio you would rather not
# commandeer. Startup says so every boot.
#
# Both of these are required rather than optional on purpose: running blind or silent
# has to be asked for, so a config that lost a line fails loudly instead of booting

# How many episodes of each podcast show to keep, newest first. A show that has

# 5.8 GB, which will not sit next to the rest of a library on a Pi's SD card.
#
# The same number caps what gets downloaded, which is what makes the folder settle.
# Prune to the newest N but fetch everything the feed offers, and every poll would
# re-download the episodes the last one deleted.
#
# Lowering this DELETES the episodes that fall outside the window on the next poll,
# and an episode that has aged out of its feed cannot be fetched again. Use `null` to
