/**
 * Whether the host has muted remote screenshare AUDIO (`io.lotus.set_deafen`
 * `screenshareAudioMuted`). Consumed by `LivekitRoomAudioRenderer` exactly the
 * way `muteAllAudio$` is: it becomes the `muted` prop of every
 * `Track.Source.ScreenShareAudio` element, so it survives re-renders, applies
 * to tracks that are published LATER (a sharer stopping and re-sharing, a late
 * joiner) and never fights EC's per-tile volume controls — which was the
 * failure mode of the old `RemoteParticipant.setVolume(0, ScreenShareAudio)`
 * approach: `createVolumeControls` writes its own volume (1) through the same
 * sink the moment a new screenshare media item appears, un-muting it.
