- activeSeason now returns the first season (Season 1 'First Bloom') so a new
player starts at spring instead of the newest season.
- Bundle the owner-picked CC0 tracks menu.mp3 + season_001.mp3 (BGM now audible).
- Settings footer shows 'v1.0.0 (build 3)' so test builds are identifiable.
180 tests green, analyze clean.
