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`.

75b0eed080 Remove the Quallenalarm (jellyfish) typing minigame 
Letters-round lessons only had bubbles and jellyfish as eligible arcade
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.

/* 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">

* // 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.

"""Where analysis actually burns CPU, and how it is kept from taking the machine over.
Analyzing one track is a few seconds of single-threaded DSP that the GIL will not let
another Python thread overlap with - librosa's work is numba-jitted and numpy glue, not
long C calls that release it. So a library-sized pass parallelizes across *processes*:
:func:`analysis_pool` hands :meth:`~musicmouse.library.MusicLibrary.analyze_pending` an
executor whose workers are separate interpreters, and a 12-core desktop chews through a
first-time scan roughly an order of magnitude faster than the Raspberry Pi this also
has to stay polite on.
Polite means three things, all of them set here rather than at the call site:
* **One core stays free** (:func:`default_worker_count`), so the audio thread and the
web server never have to fight a full house of analyzers for a timeslice.
* **Workers run niced**, so even the cores they do own yield to playback instantly.
* **Each worker stays single-threaded** - numpy's BLAS and numba would each happily
start one thread per core *inside* every worker, and N x N threads on a 4-core Pi is
slower than N, not faster.
Whatever an analyzer returns has to survive the trip back from a worker process, which
is what keeps :class:`~musicmouse.library.analysis.TrackAnalysis` and friends plain
frozen dataclasses of floats. An analyzer that records state in its own instance -
a test double counting calls, say - only sees that state in the worker, so such an
analyzer must be run with ``workers=1``, where everything stays in this process on a
thread.

# Musik Delfin — the Slint front-end
A native front-end for the music player, next to `../web/`. Same backend, same layout,
same German copy; no browser. It exists because the React UI is sluggish on the Pi 5
kiosk, and the things making it sluggish are browser-shaped: a compositor deciding what
gets its own layer, a `requestAnimationFrame` loop that repaints the viewport, and a
JPEG decode per album card per cold start.
The music player and the room panel ("Mein Zimmer"). The typing game (`Tippen`), parent
mode and the IR-remote assignment are still web-only.
## Running it
Start the backend, then:
```sh
nix-shell # cargo, the GL/X11/Wayland libs, and Nunito
cargo run # windowed, FemtoVG
cargo run -- --server http://musicdolphin:8080
cargo run -- --page room # open on the room panel rather than the player
```
Checks:
```sh
cargo test && cargo clippy --all-targets && cargo fmt --check
```
`tools/headless-shots.sh` renders the UI and screenshots it inside a nested headless
compositor, for checking a layout change on a machine with no display (or a locked one).
A Slint window needs a real compositor - under bare Xvfb nothing maps at all.
## Build profiles
| | Backend | Renderer | For |
|---|---|---|---|
| `cargo run` | winit | FemtoVG | development here |
| `cargo run --features skia` | winit | Skia | checking what the device will show |
| `cargo build --release --no-default-features --features kiosk` | linuxkms + libinput | Skia | the Pi |
**The device must not use FemtoVG.** On a Pi 5 (Mesa V3D), FemtoVG draws every
runtime-loaded `Image` as solid black - [slint#11785][bug], open as of this writing -
which for this app means every album cover. Skia and the software renderer are both
unaffected. FemtoVG stays the default *here* because it builds in seconds and is fine on
desktop Mesa; `kiosk` is the profile that ships.
`--no-default-features` is not optional on that last one: the features are additive, so
leaving `desktop` on would link winit *and* linuxkms into the same binary.
`kiosk` takes the framebuffer directly through KMS/DRM: no X, no Wayland, no compositor.
(`backend-linuxkms-noseat` is deprecated upstream in favour of the libinput variant used
here.) `SLINT_BACKEND=winit-software` forces the software renderer without a rebuild.
[bug]: https://github.com/slint-ui/slint/issues/11785
## Where the speed comes from
Four things, in rough order of how much they matter on the device:
**Covers are downscaled once, ever.** The backend serves one size - 640 px on the long
edge - and has no `?size=`. A grid card is 180 px. `src/covers.rs` fetches each cover
once on a worker thread, resizes it to the tier that was asked for, and writes a JPEG
thumbnail to `~/.cache/musicmouse-slint/covers/<album-id>@<px>.jpg`. Every later start
reads that instead. There are two tiers and only two, which is what makes the cache
worth having: a per-widget pixel size would give each album a dozen near-identical files
and a fresh decode for each.
The cache is dropped wholesale when the websocket announces a rescan
(`{"type": "library"}`), because that is the one moment the backend rewrites the art
behind an unchanged cover URL. That is the bug the web client had to learn about the
hard way - see the comment at `python-backend/musicmouse/services/web/api.py:106`.
**The grid is virtualized.** Rust hands the UI a `[GridRow]` - the album list
pre-chunked into rows - and the view puts those in a `ListView`, which only instantiates
the rows on screen. A flat list of 660 cards gives it no rows to skip, hence the
chunking. This is the counterpart of `content-visibility: auto` on `.grid > .card` in
the web UI, which exists for exactly the same measurement: 340 live cards saturated the
Pi's renderer so completely that the main thread stopped scheduling anything.
**The progress bar animates instead of ticking.** Position arrives twice a second. The
web client interpolates it onto animation frames with a JS clock and a render budget;
here the fill is a Slint `animate width` between the pushed values, so interpolation
costs a property evaluation per frame on the render side and there is no clock at all.
It is suppressed for the one frame a track changes on, so a new track jumps rather than
sliding across two unrelated positions.
**Nothing on screen animates by itself.** The web UI's per-track ambient canvas is not
here. Halving its resolution and its frame rate took it from 53.5% of a core to 25.0%
and 25% was still too much: a loop repainting the viewport is a floor you cannot get
under while it runs at all. The stage keeps its gradient, which is what `?pi=1` already
does on the device this replaces.
## What is deliberately different from the web UI
**No glass blur.** Slint has no `backdrop-filter`, so the panels use a flat translucent
fill - exactly the web app's own `data-blur="off"` fallback. Some depth is genuinely
lost. Faking it by compositing a pre-blurred copy would reintroduce the per-frame cost
that dropping the blur was meant to avoid.
Worth knowing if you ever port the blur back: on the Pi, `backdrop-filter` measured five
times *better* than no blur (25% of a core against 118%), because it is what promotes
each panel to its own compositing layer. That is a browser-compositor artifact and does
not transfer here - but it is why the web UI keeps the panel blur under `?pi=1`.
**No dolphin.** The mascot and its swim/bob loops are not ported.
**Layout** is Slint's, not a transcription of the CSS: fixed row heights instead of
`clamp()` and `vh`, a 1080p-shaped fixed measure for the track list rather than
`max-width`. The colours are the same - `ui/theme.slint` carries the web UI's oklch
tokens converted to sRGB, with the oklch source kept beside each one, because oklch is
the form the design is actually maintained in.
## How it is put together
The split that matters is the web UI's, unchanged: **what is playing** comes from the
backend, **what you are looking at** lives here. The buttons on the mouse, a figurine on
the reader and Home Assistant all move playback too, so this follows it rather than
assuming it is in charge.
Three worker threads and no async runtime - the whole client makes one library request,
one websocket connection and a trickle of covers.
| Path | What it is |
|---|---|
| `src/api.rs` | The wire types and the HTTP calls. Mirrors `services/web/schemas.py`. |
| `src/ws.rs` | The state websocket, with reconnect-and-reseed. |
| `src/library.rs` | The search index and the browse hierarchy. Port of `web/src/lib/search.ts`. |
| `src/keymap.rs` | The keyboard model, as a pure function. Port of `web/src/lib/keyboard.ts`. |
| `src/covers.rs` | The thumbnail cache, and the generated stand-in art. |
| `src/ha.rs` | Home Assistant through the backend's proxy, and the shutter/colour conversions. Port of `web/src/hooks/useHomeAssistant.ts` and `lib/shutter.ts`. |
| `src/oklch.rs`, `src/format.rs` | Colour conversion; durations. |
| `src/main.rs` | Wiring: worker channels in, Slint models out. |
| `ui/*.slint` | Layout only. Nothing here formats a number or picks a word. |
`src/keymap.rs` and `src/library.rs` are ports of modules that were already pure
functions with their own tests, and they keep them: 43 tests, no window required.
## Keyboard
The same map as the web UI.
| Key | |
|---|---|
| `SPACE` | play / pause (types a space mid-query) |
| `SHIFT+H` / `SHIFT+L` | previous / next |
| `SHIFT+J` / `SHIFT+K` | quieter / louder |
| `SHIFT+M` | mute |
| `SHIFT+←` / `SHIFT+→` | seek 15 s |
| `A-Z`, `0-9` | search albums as you type |
| `?` | search individual tracks |
| `TAB` | cycle Musik / Hörbücher / Podcasts |
| `← ↑ ↓ →` | move the selection while browsing; transport and volume while playing |
| `CTRL+H/J/K/L` | the same, without leaving the home row |
| `CTRL+D` / `CTRL+U` | half a page |
| `ENTER` | play the selection |
| `SHIFT+ENTER` | open the track list |
| `ESC` | back out one layer at a time |
| `/` | back to browsing |
| `CTRL+TAB` | cycle Musik / Mein Zimmer / Tippen |
Everything is clickable too.
`CTRL+TAB` is the one addition to the web front-end's map. Its tab rail is reachable
only with a pointer, which sits badly with a device whose stated design is that every
screen can be reached from the keyboard. Plain `TAB` was already the group cycle.
## Mein Zimmer
The Home Assistant room panel, in its own violet rather than the player's teal so the
two read as siblings. Lights get a toggle, five brightness steps and six colours;
shutters get four presets, up/stop/down and a window that reflects the reported
position. Nothing is animated locally - a real cover reports its own movement, and
guessing where it will end up is what would fight with that.
The whole page is a poll, not a subscription, and only while it is on screen: Home
Assistant's own auth-and-subscribe websocket is more machinery than this needs, and a
lamp is not worth a request every 2.5 s when nobody is looking. A tap patches the
entity locally and remembers when, so the poll already in flight cannot undo it - the
same reconciliation `useHomeAssistant.ts` documents, and for the same reason.
The tab appears only when the backend answers `GET /api/ha` with a config; a 404 there
means Home Assistant is not set up, which is a normal answer rather than an error.
The special keys are named in `ui/app.slint`, where the `Key.*` constants live, and
reach Rust as `"escape"`, `"left"`, `"enter"` and so on - so `src/keymap.rs` is testable
without a window and without hardcoding keysym values.
## Fonts
Nunito, via `SLINT_DEFAULT_FONT`, which `shell.nix` sets. Slint cannot read the woff2
the web app self-hosts, so this wants the TTF; a deployment can drop one at
`fonts/Nunito.ttf` instead. With neither, everything still renders in the system sans.

Nunito, the face the design is drawn in, as a variable TTF.
`web/public/fonts/` has the same family as woff2, which is right for a browser and
useless here: Slint cannot read woff2. This is the upstream variable TTF (weights
200-1000), which `SLINT_DEFAULT_FONT` is pointed at - by `shell.nix` for development,
and by the launcher `roles/pi_slint_frontend` installs on the device.

//! Browsing and searching the library, entirely on the client.

//! The whole index arrives in one response, so type-to-search has no round trip - which

//! the reason that module is shaped the way it is:
//!
//! The cost that matters is per keystroke, not per library load. A real collection is
//! 343 albums and 4969 tracks, and the naive version re-derives its search keys from
//! scratch on every one of them for every letter typed - `normalize` runs a lowercase,
//! a Unicode NFD decomposition and two filtering passes, so track search would mean
//! five thousand NFD normalizations before a single comparison. That is work whose
//! answer cannot change until the library does, so it happens once, in
//! [`Library::build`], and a keystroke becomes `str::contains` over strings that
//! already exist.

Podcast issues:
- cover art for podcasts:
- use the coverart embedded in the actual mp3
- use generic image or cover.jpg inside the podcast folder
- download a cover.jpg for the podcasts already in the library right now
- podcasts grouping right now is not optimal. right now the hierarchy is for example "Sendung mit der Maus" => "Sendung mit der Maus" => "actual tracks". I'd rather like: "Sendung mit der Maus" => all tracks shown as separate cards so that their cover art is shown. The normal track list view (textbased) should be replaced by this.
- when playing a podcast, the timer "Noch ... im Hörbuch" doesn't make sense. Hide it in case of podcasts. also stop playing after one podcast episode. For albums and real audiobooks stop after the audiobook or album played fully.
think about a datamodel for podcasts that is elegant, fits with what we have and then check back with me before implementing.
UI issues:
- setting the volume reacts very slowly right now. investigate. fix only if it is possible without massive workarounds.
plan a fix and check with me first.
- the seek bar is behaving weird: when I click on a position it moves there, but then it moves sligtly backwards (probably after a backend state update). Find the cause and check the fix with me before implementing.

Only the pure modules are tested - the search, the keyboard machine and the time
formatting. That is where the behaviour lives; the components are mostly layout.
`src/lib/search.ts` builds its normalized search keys once per library payload
(`buildSearchIndex`) rather than per keystroke. It matters more than it sounds: a real
collection is 343 albums and 4969 tracks, and `normalize()` does a Unicode NFD
decomposition, so track search used to mean five thousand of those before a single
comparison - 4 ms per keystroke on a laptop, and this runs on a Pi. The same build also
partitions albums by shelf and pre-sorts each shelf's categories, which `App` and
`BrowseView` were otherwise deriving separately from the same data.

`SHIFT+arrows` is the one addition to the mockup: plain arrows were already taken, and
seeking is the one thing a real player can do that the mockup could not.
## The Raspberry Pi profile
`?pi=1` loads the same app with nothing on screen animating itself. It exists for
musicdolphin - a Pi 4 driving a 1920x1080 kiosk screen.

| `backdrop-filter` on cards and list rows | on | off |
| `backdrop-filter` on panels | on | **on** |
| Progress-bar re-renders | every animation frame | 10 per second |
Two of those rows are worth knowing the reasons for, because both are the opposite of
what they look like.
**The panel blur stays on.** Dropping it measured *five times worse* on the device -
118% of a core against 25%. `backdrop-filter` is what promotes each glass panel to its
own compositing layer; without it the panels and everything under them collapse into
one layer that repaints wholesale. The card blur goes because that is a different
problem: three hundred of them in one grid, not one per panel.
**The canvas goes away rather than getting cheaper.** Half resolution and 30 fps took
it from 53.5% of a core to 25.0%, 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. `.stage` keeps its own static CSS gradient, so there is still a
sea behind everything - it just no longer moves or follows the track.
`AMBIENCE_QUALITY` in `src/lib/lowPower.ts` is kept accurate for whoever turns the
canvas back on.
The flag is read once at module load from the URL and nowhere else - no persistence, no
auto-detection. That is what makes "is this the profile or the hardware?" answerable by
editing the address bar. The kiosk gets it from `pi_kiosk_url` in the ansible repo.
