Applies rule 32's migration exception: each header still says what the
schema was, what changes and what it prevents, but task, milestone,
decision and rule ids are replaced by the practice they stood for, the
operator quotes by the decision, single-install counts are dropped, and
pointers to a deleted package and an external design doc are gone.
golang-migrate keeps no checksum, so editing applied migrations'
comments is safe.

Mode (off, auto, track, album), target (-18, -16, -14 LUFS) and boost
(within headroom, or fully with a limiter), stored per user on the server
so the web player, the Android app and casts apply the same one.
- Server: user_normalization_prefs (migration 0067), GET/PUT
/api/me/normalization; a whole-body PUT, validated, last write wins.
- Web: Settings > Playback > Volume leveling. Saves at once, restores the
old choice if the save fails, and caches the value for the player.
- Android: Settings card. The device keeps a copy for offline playback
(Room v9 with an explicit migration, so the upgrade wipes nothing).
Writes are offline-first: shown at once, PUT best effort, queued on
failure (NORMALIZATION_SET, collapsed to the newest). A refresh never
overwrites a change still queued.
