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.

Build a single index.html with Three.js solar system. Check three.min.js exists and version quickly.
bash {"command":"ls -la /workspace && head -c 300 /workspace/three.min.js"}

Three.js r13x (2021). Build with custom orbit controls (no OrbitControls file), starfield points, sun with emissive, planets with varied speeds/sizes, orbit rings, labels maybe. Write index.html.

Quick sanity check on JS syntax via node (extract script). Simple check: node --check on extracted inline script.
bash {"command":"cd /workspace && node -e \"\nconst html=require('fs').readFileSync('index.html','utf8');\nconst m=html.match(/<script>([\\s\\S]*
toolResult

JS syntax OK

Done — `index.html` is a fully self-contained 3D solar system built on the local `three.min.js` (no network, no external assets). **Features:** - **Sun** — pulsating sphere with layered additive glow sprites + point light illuminating the scene - **8 planets** — varied sizes, colors, orbital distances, and speeds (Mercury fastest → Neptune slowest), each with a visible orbit ring, slight orbital tilt, and self-rotation; Saturn has its ring, Earth has an orbiting Moon - **Starfield** — two counter-rotating point clouds (~3,700 stars) in white and blue tints - **Camera controls** — custom drag-to-orbit, scroll/pinch zoom, right-drag/Shift-drag pan - **Extras** — raycast hover to show planet names, time-speed slider (0–5×), responsive resize Syntax verified. Just open `index.html` in a browser.

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.
