Generator: raise the early bot-win-rate floor to ~0.97 (near-guaranteed first
stages), widen the early move-buffer margin, and delay score-chase/line-sprint
objectives until stage 9/13 so the opening stretch is pure clear-a-gem. Result:
stage 1 now 16 moves (was 11), stages 1-9 all simple gems at 90-99% bot win.
Preserves theme.bgm=season_001; manifest SHA regenerated. Settings tag -> build 4.
MusicService (looping audioplayers player, independent of SFX) driven by the
active season theme's new 'bgm' key; switches track on season change, pauses on
app background, all failures swallowed. Separate Music on/off toggle in Settings
(persisted, independent of SFX). Season packs carry bgm keys (menu/season_001/
season_002), manifest regenerated. Assets slot assets/audio/bgm/ ready — drop in
menu.mp3/season_001.mp3/season_002.mp3 (CC0) and it plays; silent until then.
180 tests green, analyze clean.

Greedy bot with tray-survival lookahead and gem-line steering; generator
samples layouts along a difficulty curve, probes bot moves-to-win, sets
adaptive move budgets targeting win-rate bands, and derives star
thresholds from spare-move quantiles. Season 1 pack bundled in assets
with per-stage difficulty report.
