Using the pre-provided three.min.js (global THREE), build a 3D solar system with the sun and orbiting planets at varied speeds and sizes, orbit-drag camera controls, and a starfield.

The user wants a single-page 3D solar system using the pre-provided `three.min.js`. Let me first check what's available in the directory, then build the complete `index.html` file with: 1. A starfield background 2. The sun (glowing) 3. Orbiting planets with varied sizes and speeds 4. Orbit controls for camera I need to check if there are any other files that might be needed - like an orbit controls library. Let me look at the directory first.

Only `three.min.js` is present. Since it's the minified version, OrbitControls might not be included in it (it's often a separate file). Let me check if THREE.OrbitControls is bundled or if I need to implement orbit controls manually. With just the minified three.min.js, OrbitControls is typically NOT included. I'll implement a custom orbit-drag camera control system using mouse events — this is actually cleaner and more self-contained. Let me build the complete solar system with: - Custom orbit camera controls (drag to rotate, scroll to zoom) - Starfield rendered as points/sprites - Sun with emissive glow effect - Planets with different sizes, colors, orbital distances, and speeds - Orbital path visualization - Proper 3D rendering with Three.js Let me write the full index.html now.

I need to fix a bug - the moon is being added to the tiltGroup on every frame inside animate(). Let me fix that, and also there's a typo in Jupiter's texture. Let me re-read and fix these issues.
Let me fix a couple of bugs I noticed — the moon was being double-added each frame, and there's a typo in Jupiter's band color:
{"path":"/tmp/ws/index.html","edits":[{"oldText":" tilts:0.05, draw:(ctx,w,h)=>{\n const bands=['#c4a46a','#a67c4a','#d4b87a','#Successfully replaced 2 block(s) in /tmp/ws/index.html.

Good. Let me verify the file is complete and valid by checking the end of it.
{"command":"tail -20 /tmp/ws/index.html && echo \"---\" && wc -l /tmp/ws/index.html"}// Hide label when behind camera if (screenPos.z > 1) { p.labelEl.style.display = 'none'; } else { p.labelEl.style.display = ''; p.labelEl.style.left = x + 'px'; p.labelEl.style.top = (y - p.def.r * 10 - 8) + 'px'; } }); updateCamera(); renderer.render(scene, camera); } animate(); })(); </script> </body> </html> --- 478 /tmp/ws/index.html

The file looks good. Let me verify it's well-formed by checking for any syntax issues.
`/tmp/ws/index.html` is ready — 478 lines, fully self-contained with no network requests. Here's what's in it: ### Solar System Features | Feature | Details | |---|---| | **Sun** | Large emissive sphere with procedural texture + additive-blend glow sprite | | **8 Planets** | Mercury → Neptune — each with unique procedural textures (bands, spots, ice caps, clouds) | | **Orbital speeds** | Proportionally varied (Mercury fastest at ~4× Earth, Neptune slowest at ~0.6×) | | **Planet sizes** | Jupiter largest (r=4.5), down to Mercury (r=0.6), scaled for visibility | | **Saturn rings** | Semi-transparent ring geometry with radial gradient texture | | **Earth's moon** | Small orbiting moon around Earth | | **Starfield** | 8,000 color-varied background stars spanning a large sphere | | **Axial tilts** | Each planet has its own realistic axial tilt rotation | | **Orbit lines** | Subtle white orbital path guides | ### Camera Controls - **Left-drag** → orbit around scene center - **Right-drag** → pan camera target - **Scroll wheel** → zoom in/out (clamped) - **Touch** → single-finger orbit, two-finger pinch-zoom ### Labels Each planet has an HTML label overlay that tracks world→screen position and hides when behind the camera. Hover for highlight effect.

EVALUATION
Solar system with sun, orbiting planets, starfield, and orbit-drag camera controls all respond correctly to 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.
