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.

The user wants a single-page web app with Three.js that renders: 1. A full-screen scene 2. A rotating icosahedron 3. Two colored point lights 4. Orbit-style auto-rotation 5. A subtle starfield background All in one `index.html` file, using the already-present `three.min.js` file. Let me build this. I need to use the global THREE from three.min.js. Let me create a nice scene with: - An icosahedron geometry (maybe with some nice material) - Two point lights with different colors (e.g., cyan and magenta) - Auto-rotation (I can implement this manually since we might not have OrbitControls loaded - I'll make the camera orbit or the object rotate) - Starfield background (particles) - Full-screen canvas Since we don't have OrbitControls as a separate file, I'll implement auto-rotation by rotating the mesh and maybe also moving the camera in a circular path. Or I can just rotate the icosahedron on multiple axes and have the camera slightly orbiting. Let me create this.

The file has been written successfully. Let me verify it's there.
The file is written. Here's what the scene includes: - **Full-screen canvas** — fills the viewport, handles resize, dark background with subtle exponential fog - **Icosahedron** — detail level 1 with flat shading, metallic material, plus a faint wireframe overlay and a gentle scale "breathing" animation; rotates on both axes - **Two colored point lights** — cyan (`#00ccff`) and magenta-pink (`#ff2288`) orbiting the icosahedron on different paths, each with a small glowing sphere marker; plus a dim ambient fill - **Orbit-style auto-rotation** — the camera slowly orbits the center, bobbing gently in the Y axis while always looking at the origin - **Starfield background** — 3000 particles spread in a sphere at distance, with slight color variation (warm whites/cool blues), additive blending, and slow rotation for parallax Everything loads from the local `three.min.js` — no network or CDN required.

EVALUATION
Rotating icosahedron with pink/cyan point lights and starfield background continuously animates; auto-rotation constant regardless of input.

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.
