Flesh out the 14 still-open issues (GAL-34/35/36/37, 40/41, 43, 46/47/48/49, 52/53/55) with explicit acceptance criteria and concrete integration test hints that reference existing types and headless tooling, so future work on these tickets has a clear definition of done.

# GAL-49: Add background music
|
|
|
|
Add background music.
|
|
|
|
## Acceptance criteria
|
|
|
|
- [ ] Music begins on entering `GameState::Playing` and stops/pauses on `GameOver` and `StartMenu`.
|
|
- [ ] Re-entering `Playing` (after restart) starts exactly one music instance — no overlapping tracks.
|
|
- [ ] Music volume control independent from SFX channel.
|
|
- [ ] Looping is seamless (no audible gap on loop).
|
|
- [ ] Optional: per-stage track override defined in `StageConfig`.
|
|
|
|
## Integration test hints
|
|
|
|
- State-transition test: `OnEnter(GameState::Playing)` → assert one `BgMusic`-tagged audio entity exists; `OnExit(Playing)` → assert it is gone or paused.
|
|
- Restart loop test: Playing → GameOver → restart (GAL-55) → Playing; assert exactly one music entity at the end (no duplication).
|
|
- Headless: ensure the music asset loads under `nix develop` without blocking startup.
