Good, three.min.js is present (~600KB). Now I need to build a complete single-page 3D solar system with:
1. Sun and orbiting planets with varied sizes and orbital speeds
2. Orbit/drag camera controls (since we can't use OrbitControls from CDN, I'll implement basic orbit controls manually)
3. A starfield background

Let me create the index.html with everything inline.

Building the solar system now.

The file has been written successfully. Let me verify it's in place and looks correct by checking the file exists and has reasonable content.

Done. Let me verify the file is in place.

The user hasn't asked a follow-up question - the previous task is complete. The `index.html` file has been written successfully at `/tmp/ws/index.html` (10,779 bytes). Let me summarize what was built.

The `index.html` is ready at `/tmp/ws/index.html` (~11KB). Here's what it includes: **Solar System Features:** - **Sun** — glowing radial gradient sphere with emissive material and point light casting shadows - **8 planets** (Mercury through Neptune) — each with unique sizes, orbital distances, colors, and speeds: - Earth has a procedurally generated texture with oceans/clouds + a **moon** orbiting it - Jupiter has banding patterns and a surface spot - Saturn has a **tilted ring** made from `RingGeometry` - **Orbit trails** — faint circular lines showing each planet's orbit path (toggle with **T** key) - **Starfield** — 12,000 randomly placed points spanning 2000 units **Orbit Camera Controls (fully manual — no OrbitControls dependency):** - **Mouse drag** — orbit around the scene (horizontal/vertical rotation) - **Scroll wheel** — zoom in/out (15–500 units) - **Touch support** — single-finger drag orbit + pinch-ready **Controls:** - `T` — toggle orbit trail visibility - `+` / `-` — increase/decrease animation speed Everything uses only `three.min.js` (the global `THREE`) loaded via `<script src="three.min.js">` — no CDNs, no network requests, entirely self-contained.
