The prompt

Build a single-page WebGL2 (no WebGPU) reaction-diffusion simulator (Gray-Scott) that grows coral/brain-like patterns on a 512x512 ping-pong framebuffer, rendered with a lit, height-shaded material and a slow orbiting camera over a 3D displaced plane (Three.js allowed). Include presets (coral, mitosis, worms, spots), a brush to seed chemicals, feed/kill sliders, and pause/reset. IDLE AUTO-PLAY: with no input it starts from a random seed, cycles presets every 12 s, and keeps the camera orbiting so a headless capture shows continuous growth. Single index.html, no build step, CDN imports only, 60 fps target. Save the main page as index.html in the current directory (plus any local asset files you create), with no build step. You may serve it locally and open it in headless chromium (/usr/bin/chromium, software WebGL, no GPU, no WebGPU) to screenshot and inspect your own output, and iterate on your own before finishing. Close any browser you open as soon as you've taken your screenshot. Finish with a short README.md describing the controls.
