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".

A play is recorded when a new track starts (pausing and resuming doesn't
count; returning after 10+ minutes does). Profiles show the last 10,
excluding the track playing now; 50 are kept per user. Recent plays are
free on every plan; the paid flag is renamed to fullHistory.

- Shared: link building, feed ordering, input schemas, API client
- API unit: track matching, private-address blocking, token crypto,
plan expiry, provider response parsing
- API integration against Postgres and Redis: auth, follows and pins,
now-playing state, webhooks, OAuth return URLs, realtime, rate limits
- Tests use a dedicated *_test database and Redis DB, and refuse to wipe
anything else; fetch is stubbed so they never hit the network
- Pin Node to 22.13+ (.nvmrc), which Vite's native bindings require
