The prompt

Build a single index.html real-time procedural sun using volumetric raymarching in a fragment shader (Three.js or raw WebGL2). Include animated plasma granulation from 3D noise, limb darkening, a glowing corona with flares and prominences, and bloom. Add a UI for temperature (colour shift), turbulence and flare intensity. Orbit camera. No external assets. IDLE AUTO-PLAY: with no input, the page starts animating immediately and runs an automatic demo (camera motion, preset or seed cycling, or an AI player) so a headless capture shows constant motion. Must render on WebGL/WebGL2 with no WebGPU required. 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.
