momentchan/false-earth — reverse-engineered prompt

Build me an interactive browser art experience called False Earth.

I want a playable astronaut exploring an endless strange landscape that looks Earth like at first, but shifts and reacts as you move. The ground should have dense procedural grass that bends or pushes away around the character, rolling terrain that feels continuous, flowers or rose like animated details, wind, atmospheric cosmic beam effects, and cinematic post processing like bloom and depth of field.

Make it run as a modern TypeScript web app using React Three Fiber and Three.js WebGPU. Use GPU based simulation for the grass and terrain where it makes sense, with level of detail so it can stay smooth. Include third person movement, camera options like follow and first person, keyboard and touch input if practical, a loading screen, audio controls, and graceful messaging if WebGPU is not supported.

Please set up the project so I can run it locally with npm install and npm run dev. Look up current docs online if you need to.
