"""Shared fixtures for v2 ``.alfred`` integration tests.

The fixtures here build realistic ``SeriesRelease`` / ``MovieRelease``
aggregates — populated tracks, multi-episode files, both PACK and
EPISODIC modes — so every test starts from a known-rich state.
The point is to make round-trip tests genuinely lossless-checking
(if a field is unused in the fixture, the round-trip can't prove
much about it).
