Add POST /api/power/:action (reboot|shutdown) that runs `sudo systemctl
reboot|poweroff` (sudo is passwordless on the appliance), replying before the
host tears down. Two red buttons in the Output tab use a two-tap confirm to
avoid accidental power-offs.

Expose the engine's live-input mode on the remote: an "Sorgente audio"
selector in the Audio tab lists the input devices the output reports and
switches between File/Playlist and a live USB capture (useInput); picking
File again stops the input. Grant the kiosk getUserMedia access with
--use-fake-ui-for-media-stream so device enumeration/labels work without a
prompt. Make reportDevices resilient (per-probe timeout, always report even
an empty list) so the UI gets feedback when no input is connected yet.
The Pi 5 has no audio input — a USB (line) sound card is required; visuals
react to the source while the audio stays on the mixer.

Port the Mac app's scene system to the phone control. Each queue entry is
now an independent clone carrying a `cues` list of timed elements (effect /
text / image), each with its own appearance time and visible duration; the
three channels are driven independently from playback progress (advanceCues).
Add visual-only "Intermezzo" queue items (silence audio, run their scene for
a set duration) and make the inter-track gap keep the scene running. New
mobile scene editor lives in the queue card detail (⚙). The queue (with
scenes) is persisted via saveState so it survives a phone reload.

Android/iOS Chrome grey out audio files when the document provider reports
a generic MIME (e.g. application/octet-stream for mp3 in Downloads), so
accept="audio/*,video/*" alone hid them. Add explicit extension tokens
(.mp3, .m4a, …) which mobile pickers honour by filename, un-greying them.
Also surface upload success/failure on the button instead of silently
resetting.

The Pi 5 vc4hdmi exposes only IEC958 and has no hardware mixing, so raw
ALSA is exclusive: once Chromium's Web Audio stream holds the HDMI device,
the media-element audio (the actual track) can't open it and stays silent
even though the analyser sees the signal. Install PipeWire + pipewire-pulse
as a software mixer (it also handles the IEC958 conversion) so every
Chromium stream mixes onto HDMI. Enable lingering so the user services
start at boot; set the HDMI sink to full volume.

Root cause of 'track does not start': the server re-broadcast incoming frames as
binary (Buffer), so the browser output page received Blobs, JSON.parse failed,
and every command (playTrack, etc.) was silently dropped — only the text-encoded
lastEffect sync got through. Broadcast as text now; net.js also handles Blob
defensively. Also: no-store for app assets + kiosk --disk-cache-size=1 so
redeploys always take effect; /api/clients debug endpoint; /api/peaks duration.

- Queue cards expand to a detail panel with the waveform, elapsed/total/remaining
times, draggable in/out handles, scrub-to-seek and a 'pausa dopo' gap.
- /api/peaks now also returns exact duration (samples/8000) so non-playing tracks
have correct times/trim without relying on the output media probe.
- Service worker switched to network-first (+v2) so UI updates aren't masked by
a stale cache; output.js probeDurations hardened (load()+timeout fallback).

- Drop --use-gl=egl (disabled the GPU on Chromium 149) and let Chromium pick the
default ANGLE/GLES backend with --ignore-gpu-blocklist -> hardware WebGL2.
- Launch kiosk via 'cage -- bash kiosk.sh' so a non-executable bit after rsync
no longer breaks startup.
- output.js reports gpuInfo (webgl2 + renderer) on load for remote diagnostics.

New separate project (the Electron Mac app stays untouched). Reuses the visual
engine (WebGL shaders, effect catalog, Web Audio) verbatim and replaces Electron
IPC with a Node HTTP+WebSocket server:
- server.js: serves the kiosk output page + mobile control PWA, relays the same
ctl/rpt JSON protocol over WebSocket, plus REST for media library/upload,
JSON state (pads), waveform peaks and MP4 recording (ffmpeg).
- public/js/net.js: window.djv shim over WebSocket+HTTP so output.js runs intact.
- public/index.html + control.js: touch-first mobile remote (effects, media/queue,
ticker, pads, audio/EQ, fullscreen + recording).
- PWA (manifest + service worker + generated icons).
- scripts/: Chromium kiosk launcher + install-pi.sh (systemd units for Pi 5).
Verified: REST endpoints, WebSocket relay both directions, control PWA loads the
2958-effect catalog and renders. (Headless WebGL output not testable without GPU.)
