A reboot kills Chromium rather than closing it, so it writes "exit_type":"Crashed" into
its profile. On the next boot it came up with a restore prompt and a tab stuck for ever
on a blank "Loading..." page - navigation never committed, navigator.serviceWorker was
still undefined, nothing on screen. On a device with a monitor and no keyboard that is
permanent, and the backend was healthy throughout: / answered in 5 ms and /api/library
returned 812 kB the whole time.
--disable-session-crashed-bubble hides the prompt but not the state behind it, and here
the prompt showed anyway. .xinitrc now rewrites exit_type and exited_cleanly before
launching, which is the usual remedy for a kiosk that gets powered off rather than shut
down, and adds --hide-crash-restore-bubble (the current name for the flag).
Verified by rebooting and leaving it alone: the page comes up on its own with its title
and its content.

state: restarted is unconditional, so every run reported a change and bounced
smbd - which is the share the music is copied over, so a run during a transfer
would interrupt it. Start/enable it as a task, restart it from a handler the
config copy notifies.

The role left musicdolphin with an empty venv and a service crash-looping on
ModuleNotFoundError while ansible reported failed=0, because installing the
backend hung off a handler notified by the git checkout:
- the run where the checkout changed failed later on, so handlers never
flushed and the notification was dropped;
- the next run found the checkout already current, notified nothing, and
installed nothing.
Nothing ever converges from there. Make it an ordinary task that runs every
time - uv is fast when there is nothing to do, and its output says whether it
actually installed anything, so a restart is still only notified on a real
change. Give the frontend the same treatment with a cheap stat, since the build
chain has the identical hole and a device with no dist serves no UI.
Also add libjpeg-dev and zlib1g-dev: Raspberry Pi OS has a 32-bit userland,
Pillow publishes no armv7 wheel, and uv therefore builds it from source.

pi_standard_setup's defaults set `ansible_become: true`. Role defaults are
play-wide host variables, and in Ansible's precedence the `ansible_become`
variable outranks the `become` keyword - so the `become: false` on every
pi_musicmouse task delegated to localhost was silently overridden and each one
tried to sudo on the machine running ansible:
Premature end of stream waiting for become success or become password prompt
Those defaults earn their keep bootstrapping a fresh Pi, where you connect as
`pi` and become root to enable root login, so override the variable on the
delegated tasks rather than removing them.

The app grew a python-backend/ and a web/ frontend, so pi_musicmouse no
longer matches it. Rework the role:
- Install a pinned uv and build the venv with Python 3.13; Raspbian
Bookworm's python3 is 3.11 and the backend uses PEP 695 syntax.
- pip install python-backend/ instead of a requirements.txt, and take
the systemd unit straight from the checkout so it can't drift.
- Build web/ on the control machine (no npm on the Pi) and rsync
web/dist over. Chain the checkout -> install -> build -> sync -> restart
steps through handlers so a run with no repo change does nothing.
- Per-host config files (config-<host>.yml); the schema now differs
between a host with a real mouse and a display-only one.
- Version to deploy is per host (musicmouse_version), no default.
Add pi_kiosk: autologin user running startx with Firefox in kiosk mode
and no window manager, for a Pi with a monitor attached. Enabled by
mediapi_has_monitor, defaulting off.
Turn musicdolphin into a display-only instance: serial and audio
simulated, driven entirely through the kiosk page.
