lucianoandClaude Opus 5.5 ab1ab89127 Phone remote: LAN web page + WebSocket, QR pairing, blackout/freeze 
remote-server.js: http + ws server (off by default, started from the panel,
port 8787 or next free), every request gated by a secret key embedded in a
QR code; the key persists in userData/remote.json so a phone's home-screen
shortcut survives restarts, 'Nuovo codice' revokes it. Phones send commands
that the panel executes through its own functions (transport, track pick,
effect next/prev/random/family/sequence, Auto VJ, pads, mapping on + visible
zones, blackout, freeze) and the panel pushes a compact live state at ~6 Hz
while a phone is connected (track + progress, effect, sequence, pads,
zones, meters, BPM). New panic controls in output and aux windows: blackout
(fade to black above every layer) and freeze (hold the last frame); also
available as panel buttons. src/remote.{html,css,js} is the touch UI in the
Neon Grid style, installable to the home screen, auto-reconnecting.
