//! The `MediaSource` facade (issue #347, Phase 2) over a real temp DB. Exercises
//! the local impl end-to-end through the public trait — `create_playlist` /
//! `add_to_playlist` / `set_favorite` route to the DB and read back — so the
//! facade's wiring is covered without a GUI. The remote impl needs a live
//! server and is verified against real accounts instead.
