- Feed and profile cards show a progress bar with elapsed/total time, only
when the source reports a real position (Plex, Jellyfin, the Android
reader). It ticks locally between updates. Apple Music's guessed
position is no longer reported.
- The Android reader advances MediaSession's stale position to now, stamps
when it was read (the server corrects for upload delay), and reports
seeks. The server pushes an update to watchers when a position jumps.
- When a polled source says where in the song someone is, the next poll is
scheduled just after the song ends (never sooner than 5s), instead of
waiting out the full interval.

Phones that read system media sessions report playback themselves:
- POST /me/devices issues a per-phone token that can only call
POST /devices/now-playing; revocable, hashed at rest, 10 per user
- Reports name the app ("via Spotify"); unknown apps use the OS label
- Push-reported playback expires after 9 minutes of silence, since
phones send a heartbeat every 4 minutes while playing
Users can pause sharing (PUT /me/sharing: 1h, 8h, indefinitely). While
paused, connections aren't polled, phone reports are dropped, nothing is
added to history, and the current track switches to "played … ago".
