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.

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.)
