Asset and license register

Every third-party file used by the entrance page (the world/ folder), where it came from, and the terms that were checked.

#Original work (no third-party licence involved)

The tractor-trailers, cars, pickups, drivers, trees, academy building, monument, roads,
terrain and sky presets are original procedural models written for this site. The eagle's
3D body and wing rig (js/eagle.js) are original too; its feathers are the photograph listed above.
The wind, highway, wingbeat and breeze sounds are synthesized at runtime by js/audio.js from
generated noise and oscillators; no sound files are involved apart from the eagle's call.

#Not used, on purpose

- No GSAP: scroll choreography is about 150 lines of plain JavaScript, so no extra licence or download was needed.
- No Draco, Meshopt or KTX2 decoders: they need WebAssembly, which the live Content-Security-Policy does not allow ('wasm-unsafe-eval' is absent). Adding them would be a security-policy change that needs your approval.
- Nothing is loaded from other websites at runtime: fonts, images, scripts and sound are all served from this site.
