the PTT key listeners, the deafen-key listener and useAfkAutoMute are all mounted inside CallControls, which only renders from CallView → CallJoined, i.e. only while the call room is the selected room (and, on mobile, only while the in-call chat panel is closed — Room.tsx:150 is callView && (isDesktop || !chat)). Navigate to any other room (which is exactly when the call goes to PiP), or open the in-call chat on a phone, and: PTT stops transmitting entirely, the deafen hotkey silently stops responding, and the AFK auto-mute watchdog stops running — the last one precisely in the situation it exists for (you walked away / are doing something else). The PTT cleanup also force-mutes on unmount, so a held key is dropped mid-sentence when you switch rooms.
How to trigger
join a call, hold PTT and confirm it works; navigate to another room (PiP) and hold PTT again — nothing happens. Or enable AFK auto-mute, join, navigate away, stay silent past the timeout — no mute.
Suggested fix
move the PTT/deafen key bindings and useAfkAutoMute into a component that lives as long as the embed (e.g. CallUtils in CallEmbedProvider, which already mounts per-embed) and keep only the visual PTT chip in CallControls.

### Problem
the PTT key listeners, the deafen-key listener and `useAfkAutoMute` are all mounted inside `CallControls`, which only renders from `CallView` → `CallJoined`, i.e. only while the call room is the selected room (and, on mobile, only while the in-call chat panel is closed — `Room.tsx:150` is `callView && (isDesktop || !chat)`).
