Voice commands in Wall mode

Wall mode is voice-controlled. The wake word is "Wally" — say it followed by a command. Voice recognition runs locally in the browser via the Web Speech API (free, no audio leaves the vessel).

Common commands:
• "Wally, show me Atlantic Beauty bridge cam" — switches the cam tile to the named vessel's bridge cam
• "Wally, switch to engines" — promotes the engine panel to full screen
• "Wally, zoom map" — promotes the map to full screen
• "Wally, show alarms" — promotes the alarm panel
• "Wally, return to overview" — back to the 3×3 grid
• "Wally, log <text>" — files a watch log entry with the spoken text
• "Wally, acknowledge alarm" — acks the most recent active alarm

Wake-word reliability:
The wake word fires on "Wally" with a confidence threshold tuned for typical wheelhouse ambient noise (engine room hum, VHF chatter, weather). If the system isn't recognising you reliably, increase your speaking volume slightly — the masters who use it most report the wheelhouse environment is friendlier than expected.

Privacy:
Audio is processed entirely in-browser. No audio data is recorded, transmitted, or stored on Turtini servers. Only the recognised text is sent — and only after the wake word is detected.

Manual fallback:
If voice isn't working (microphone broken, noisy environment), the bottom bar accepts typed commands too. The OOW can fall back to a wireless keyboard at any time.
