"""Guard: the test suite must NEVER resolve the real music OR video library DB.

Tests exercise modules that call get_database()/get_video_db() with no path. If
that resolves to a live DB, test writes can corrupt a real library (this
happened to BOTH the music and the video library, over a WSL-mounted Windows
drive). conftest.py sets DATABASE_PATH + VIDEO_DATABASE_PATH to temp files before
anything imports; these tests prove it sticks for every default-path access.
