A standalone 3D first-person "backrooms" environment. Procedurally generated as you walk: mostly open yellow wallpapered space with random wall partitions, occasional enclosed rooms, and long corridor stretches. The distance fades into a black void.
Built with Three.js (CDN importmap). No build step, no external assets — every texture is drawn on a canvas at startup.
ES modules need a server (opening index.html via file:// won't work):
cd temp/backrooms
python3 -m http.server 8000
# or: npx serve .Then open http://localhost:8000 and click to enter.
