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 uses three.min.js (already present in the directory) to render a full-screen scene with:
1. A rotating icosahedron
2. Two colored point lights
3. Orbit-style auto-rotation
4. A subtle starfield background

I need to write everything into one self-contained index.html file with CSS in a <style> tag and JS in a <script> tag. No external resources, CDNs, or network requests.

Let me first check if three.min.js exists in the current directory.
bash {"command":"ls -la /workspace/"}
toolResult

total 644 drwxrwxrwx 3 node node 96 Jul 22 16:55 . drwxr-xr-x 1 root root 4096 Jul 22 16:55 .. -rw-r--r-- 1 node node 603445 Jul 22 16:55 three.min.js

Good, three.min.js is present. Now I'll create the index.html file with the requested scene.
write /workspace/index.html (5359 bytes)
toolResult

Successfully wrote 5359 bytes to /workspace/index.html

The file has been created. Let me verify it exists and check the content.
bash {"command":"ls -la /workspace/index.html"}
toolResult

-rw-r--r-- 1 node node 5359 Jul 22 16:55 /workspace/index.html

The index.html file has been created successfully. It's a self-contained single-page web app that:

1. Loads three.min.js from the local directory
2. Creates a full-screen Three.js scene
3. Has a rotating icosahedron with flat shading and a subtle wireframe overlay
4. Two colored point lights (red/coral and cyan/teal) that orbit around the icosahedron
5. Orbit-style auto-rotation of the icosahedron itself
6. A subtle starfield background with 3000 stars of varying colors and sizes that slowly rotates
7. Camera has a subtle drift effect
8. Handles window resize properly

The file is complete and ready to use.

Done. Created `/workspace/index.html` — a self-contained single-page app with: - **Full-screen Three.js scene** using the local `three.min.js` - **Rotating icosahedron** with flat-shaded standard material + subtle wireframe overlay - **Two colored point lights** (coral `#ff6b6b` and teal `#4ecdc4`) orbiting the icosahedron on opposing paths - **Orbit-style auto-rotation** on the icosahedron itself (X/Y axes) - **Starfield background** with 3000 particles of varying sizes/colors, slowly rotating - **Subtle camera drift** and responsive resize handling Open `index.html` in a browser to view.

EVALUATION

3/5 working

Rotating icosahedron with starfield background and colored point lights, but the lighting looks washed out/blown-out white.

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.
