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.)
