1. Guest pre-join redesigned: brand backdrop, live camera preview, mic/cam toggles
applied on entry, initials avatar, name required, "host may admit you" note.
2. Post-admit bug: the guest stayed on "Waiting for the host…" forever — the lobby
screen had replaced the call UI and meeting-joined never re-rendered it. Now it
rebuilds the call on admission (_inLobby).
3. Audio devices: dropped the standalone headphones button. The MIC now has a ▾ caret
opening one Teams-style menu with Speaker + Microphone sections (radio-selected);
speaker uses setSinkId/LiveKit switchActiveDevice, mic switches the live input.
Mobile gets a speakerphone toggle that prefers a connected BT/headset when off.
4. Remote-control keyboard:
- Injector now maps the PHYSICAL key (KeyboardEvent.code) instead of the character,
so Shift+1 types "!" etc. Character mapping was why typing "performed differently".
- Keys reach the sharer ONLY while control is ENGAGED (window focused AND you clicked
their screen). Minimised/unfocused/chat typing stays local. Esc or clicking away
releases; modifiers are released on disengage so nothing sticks.
- Explicit control icons: viewer gets a Control ON/OFF button (green when engaged) +
an on-screen hint; the SHARER gets a control icon beside mic/chat to allow/stop
access at a glance, synced with the consent dialog and banner.
