🦾 SUIT MODE: say "suit up" for the Mark 42 HUD simulation — arc reactor, subsystem bars, flight telemetry, targeting reticle. "suit status" runs diagnostics, "suit down" powers off, ESC exits.
🎯 WAKE WORD: say "Hey A.R.C." — a chime opens a 45-second attention window; anything you say inside it is processed. After 45s of silence I return to standby (toggle in Settings, or say "wake word off").
⚡ INSTANT ANSWERS: time, date, greetings, simple math, coin flips, dice, jokes and timers answer in under 100ms — no AI round-trip.
✋ BARGE-IN: while I'm speaking, just say "stop" or "quiet" — I shut up instantly and you have the floor.
🫡 BOOT RITUAL: on power-up I report the time, live weather and system status like a proper butler.
🛎️ PRESENCE: return to this tab after 10+ minutes and I'll greet you.
