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 me to create a single-page web app (index.html) that: 1. Uses three.min.js (global THREE) - already present in the directory 2. Renders a full-screen scene with: - A rotating icosahedron - Two colored point lights - Orbit-style auto-rotation (camera orbits around the scene) - A subtle starfield background Let me first check that three.min.js exists in the current directory.
Let me first verify the three.min.js file is present, then build the scene

Good, three.min.js is present. Now I'll create a single index.html file with a full-screen Three.js scene featuring: 1. A rotating icosahedron 2. Two colored point lights 3. Orbit-style auto-rotation (camera orbits around the center) 4. A subtle starfield background Let me write this as a single self-contained HTML file.
Good, `three.min.js` is present. Now I'll build the full-screen

The file has been written. Let me verify it looks correct by reading it back and checking the key elements are present.
Let me verify the file is well-formed and contains all the required elements.

The file has been created and verified. Let me confirm all the required elements are present: 1. ✅ `three.min.js` loaded via `<script src="three.min.js">` 2. ✅ Full-screen scene (canvas fills viewport, body overflow hidden) 3. ✅ Rotating icosahedron (`IcosahedronGeometry` with `rotation.x`/`rotation.y` animation) 4. ✅ Two colored point lights (`PointLight` — one pinkish `0xff4488`, one bluish `0x4488ff`) 5. ✅ Orbit-style auto-rotation (camera orbits around origin with `cos/sin` on position, `lookAt(0,0,0)`) 6. ✅ Subtle starfield background (`Points` with 2500 particles spread in a sphere) The file is self-contained with no external CDN or network requests. All CSS and JS are inline. The task is complete.
The file is written and verified. Here's a summary of what's in `/tmp/ws/index.html`: | Feature | Implementation | |---|---| | **Full-screen** | Canvas fills viewport, `overflow: hidden` on body | | **Icosahedron** | `IcosahedronGeometry(1.5, 1)` with `MeshStandardMaterial`, rotating on both X and Y axes | | **Two colored point lights** | Pink `0xff4488` at `(4,3,4)` and blue `0x4488ff` at `(-4,2,-4)` | | **Orbit auto-rotation** | Camera orbits the origin on a radius-5 circle with slight vertical bob, `lookAt(0,0,0)` each frame | | **Starfield** | 2500 `Points` particles scattered in a sphere (r=200–800), slowly rotating | | **Self-contained** | No CDN, no network requests — loads `three.min.js` locally, all CSS/JS inline | Open `index.html` in a browser to see the scene.

EVALUATION
Rotating icosahedron with two colored point lights and faint starfield, auto-rotates continuously but appears low-poly and small.

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.
