"""Plex integration API.

Read endpoints (browse/search/stream/image/state) are available to ANY authenticated user — the
whole point of the module is to be an access layer to the Plex library WITHOUT requiring a plex.tv
account, and playback is a local file (no quota/credit cost), so demo + pure-Siftlode users are
allowed. Admin endpoints configure + test the connection and trigger a sync.

P0 ships only the admin connectivity endpoints; browse/search/player land in P1/P2.
