## Weapons (src/combat/models.js)
All four guns (pistol, SMG, shotgun, rifle), their casings and all their textures are generated in code at load: no model or texture files,
nothing downloaded, no third-party art. Generic firearm types only; no maker marks.
Judging-only reference photos (not shipped, not in the game) are listed in lanes/gameplay/weapons-state/ref/README.md.

## Gun audio (src/combat/audio.js, assets/combat/audio/guns.opus + guns.json)
One sprite file, 750 kB (Ogg Opus, stereo, 48 kHz, 36 s), cut and levelled by lanes/gameplay/tools/audiosprite.py. Everything in it is CC0
(public domain dedication; no credit required, given here anyway). Licence and author read from each page on Nov 10 2026; nothing from any game.
Everything else the module plays (thump/body layers, street tail, casings, impacts, whiz, explosion, alarm, dry-fire, draw/holster) is synthesized in code.

Not shipped: the reference gameplay audio used for measuring (lanes/gameplay/audio-state/ref-audio) and the rest of the downloaded packs (lanes/gameplay/audio-state/samples-raw).

## Heat (police, health, death): src/combat/heat.js, heatscripts.js
No outside assets. The patrol car light bar, door panels and "CITY PATROL" markings, the navy uniform, the vest and the hurt sound are made in code (our own made-up city police: no real department name, badge or livery). Officers are the kit people; their cap is the guns helper's Cap (dress.js); weapons, effects and gun audio are the lane's own.
