### Synthesized — CC0 (generated here with ffmpeg, no third-party audio)
ids: **whistle** (FM-warble pea whistle, double blast), **net** (bandpassed noise swish), **raidBust** (warbling siren). No sourced sample; original synthesis, effectively public domain.

## Notes
- No unlicensed/GPL/Zapsplat/Soundsnap/Freesound-auth content used.
- Only `crowd`/`crowdSoft` carry an attribution obligation (CC-BY); everything else is CC0.

## Ambient loops (added later, separate from the 23-sound SFX pack)

### Originally generated — CC0 / public domain (self-authored, no third-party attribution needed)
ids: **amb-rain**, **amb-day**, **amb-night** — procedural filtered-noise loops (band/lowpass-filtered
white noise, generated with ffmpeg specifically for this project, no sourced sample). Used as the
map's weather/time-of-day ambient bed (`src/shared/ambientAudio.ts`). Effectively public domain,
same as the synthesized `whistle`/`net`/`raidBust` SFX above — no attribution required.
