"""Sokhi's wrong-cover-art report: 'Vol.4' must never match 'Vol.4.5'.
Two paths served wrong art for volume-numbered series:
- the art picker's _album_matches subset check (Vol.4's tokens are a subset
of Vol.4.5's once CJK/punctuation normalizes away) — covered in
tests/metadata/test_art_lookup.py
- MusicBrainz match_release: 0.97 string similarity let the wrong volume
win, and its MBID feeds CAA art with no downstream validation — covered
here, plus the shared helper itself.
