Messaging · Calls: controls, tiles, a grid, a shared screen, a bar, a ringing dialog, a huddle

CallControls holds the microphone, camera and a shared screen as
toggles, then Leave. ParticipantTile shows a camera's frame from the
host or the person's initials, their name with a mark when muted, and a
ring while they speak. VideoCallGrid lays tiles in even rows as far as
they fit across its measured width; a short last row centers at the
full rows' width. ScreenShareView names who presents and offers Stop
presenting for your own share, the call's tiles beside or below.
VoiceCallBar tells where a call is, how long it has run and who is in
it, with the microphone and Leave. IncomingCallDialog rings with the
caller's picture; Accept or Decline answers each ring once, and Escape
declines. HuddleIndicator rings while a huddle is live; a press joins.

The recorder's device toggle and the camera's name chip now have one
home in media. People: member names sort whatever their case, a
status's words save trimmed, and a profile card's local time ticks.
