Using the pre-provided three.min.js (global THREE), render a full-screen scene with a rotating icosahedron lit by two colored point lights, orbit-style auto-rotation, and a subtle starfield background. We need to build a single-page web app, write it ALL into one self-contained file named index.html in current directory: CSS in <style> tag, JS in <script> tag, inline — do not create separate .css/.js files. Use NO external resources, CDNs or network requests: artifact runs fully sandboxed with no network. End with index.html present. These library file(s) are ALREADY present in current directory — load each with a plain <script src="NAME"></script> using its exact filename (never a CDN or URL), then build on top of it: three.min.js. Current working directory /tmp/ws. Check if three.min.js exists.

Good. Need to create index.html with script src="three.min.js". Then build scene. Requirements: - full-screen scene - rotating icosahedron - lit by two colored point lights - orbit-style auto-rotation - subtle starfield background We need orbit-style auto-rotation: likely camera orbits around object automatically. Or mesh rotates? Could be both. "orbit-style auto-rotation" suggests camera orbits. Or object rotates with orbit style? Maybe both: icosahedron rotates, camera orbits. We can implement with THREE.PerspectiveCamera, WebGLRenderer full-screen. Starfield background: points in sphere. Icosahedron: THREE.IcosahedronGeometry, MeshStandardMaterial or MeshPhongMaterial for lighting with point lights. Two colored point lights: e.g., red and blue. Auto-rotation: camera angle increment over time, or mesh rotation. Let's make mesh slowly rotate on its own axis, and camera orbit around it slowly. Full screen: canvas style width 100%, height 100vh. No external resources. Write file index.html. Make sure <script src="three.min.js"></script> before our script. CSS: body margin 0 overflow hidden, canvas display block. JS: init scene, camera, renderer, icosahedron, lights, starfield, animation loop. Starfield subtle: create Points with BufferGeometry, random positions on sphere radius ~1000. Ensure resize handler. Let's create file.

File written. We should verify it exists.

Done. Maybe we should ensure script src path correct relative. It's in same directory. Potential improvement: ensure three.min.js global THREE is available. Yes. All good. We can respond with summary.
Created a self-contained single-file app at `/tmp/ws/index.html`. It loads the local `three.min.js`, sets up a full-screen WebGL canvas, and renders: * An icosahedron with `MeshStandardMaterial` that rotates on its own axes * Two colored `PointLight`s (pink `#ff3366` and blue `#33aaff`) with subtle orbital movement for dynamic shading * Auto-orbit camera that circles the mesh while looking at the center * A subtle starfield background using `Points` on a distant sphere Resize handling and pixel-ratio scaling are included. Open `index.html` to view the scene.

EVALUATION
Rotating icosahedron with pink/blue point lights and faint starfield auto-rotates continuously; inputs don't change behavior beyond rotation state.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
