# Credits and licences

Everything in this benchmark is either our own code, MIT-licensed code, or CC0 / MIT assets. Nothing here ships in the
game without its own decision (spec § Licences).

## Textures: Poly Haven, CC0 1.0

Downloaded at 1k by `shared/fetch-textures.mjs` from `api.polyhaven.com`; `assets/textures/manifest.json` records the
file sizes and hashes. All three are by Rob Tuytel, released under CC0 1.0 (public domain dedication).
