The prompt

Build a single-page "particle life" simulation that runs in the browser on WebGL2 (WebGPU optional with an automatic WebGL2 fallback). 6 colour species, 8,000+ particles, an attraction/repulsion matrix between species that produces emergent cells, worms and orbits. UI: a small panel to randomise the matrix, pick from 5 named presets, change particle count and friction, and a live FPS readout. IDLE AUTO-PLAY: with no input, the sim starts immediately and cycles to a new preset every 8 seconds with a smooth crossfade, so a headless capture shows constant motion. Must render on plain WebGL2 with no GPU-only features required. No external accounts or API keys. 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.
