I've created a complete 3D solar system in a single `index.html` file. Here's what's included: **Features:** - **Sun** with a glowing sprite effect at the center - **8 planets** (Mercury through Neptune) with: - Varied sizes and orbital distances - Different orbital speeds (inner planets faster, outer slower) - Visible orbital path lines - Axial tilt - Saturn's rings - Earth's orbiting moon - **Starfield** with 8,000 stars in varying colors (blue-white, yellow, orange-red) - **Orbit controls**: drag to rotate the camera, scroll to zoom in/out - **Touch support** for mobile (drag to rotate, pinch to zoom) - **Smooth damping** on camera rotation - **Responsive** - handles window resizing The file loads `three.min.js` from the local directory and contains all CSS and JavaScript inline. No external resources or network requests needed.

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.
