**Reviewing Control Implementation** I've confirmed that `three.min.js` requires separate inclusion of OrbitControls, which is typical. I'm considering simple JS for mouse/touch orbit interaction or auto-rotation, or perhaps a combination for fullscreen implementation. Fullscreen is a requirement, I should re-read the requirements.

**Designing the Scene** I've got the Three.js r128 core ready, loaded with all the essentials like MeshStandardMaterial and various geometries and lights. Now, I'm thinking about designing an interactive icosahedron scene. The first step involves setting up the scene, camera, and renderer. I am looking into perspective camera parameters. **Configuring the Renderer** I'm now focusing on the renderer configuration. I've set up WebGLRenderer with antialiasing, shadow mapping (considering clean lighting options), tone mapping (ACESFilmicToneMapping), and sRGB output encoding. I've also implemented a window resize handler to update the camera aspect ratio and renderer size dynamically. **Adding the Visuals** I'm now integrating colored point lights around the icosahedron. I'm placing cyan and magenta lights that orbit in opposing directions, complete with helper spheres for visual cues. I've also added a low-intensity ambient light for improved visibility in shadowed areas. **Implementing User Controls** I've integrated orbit-style interaction to rotate the scene or the icosahedron via drag, auto-rotation for idle views, and scroll-to-zoom for adjusting camera distance. **Expanding the UI** I'm now diving into user interface elements! I'm planning controls for material styles, light color and intensity, and auto-rotation. I'm also thinking about adding a starfield toggle and preset themes. I've also added an FPS counter/info badge. Right now, I am getting ready to write a solid `index.html` with no syntax errors, responsive CSS, and cross-browser compatibility. I'm structuring it with the HTML5 boilerplate, meta tags, and a descriptive title, with styles, including a dark background and a full-screen canvas.

I have created a self-contained single-page web app in `index.html` fulfilling all your requirements: 1. **Local Three.js Integration**: Loads the pre-provided `three.min.js` (`THREE`). 2. **Full-Screen Scene**: Responsive full-screen WebGL viewport with high-DPI scaling and ACES tone mapping. 3. **Rotating Icosahedron**: Features a customizable multi-detail icosahedron mesh with metallic/glass shading and an inner glowing wireframe core. 4. **Dual Colored Point Lights**: Lit by two vibrant orbiting point lights (Cyan and Magenta by default) complete with glowing anchor orbs. 5. **Orbit-Style Auto-Rotation & Interaction**: Features continuous smooth auto-rotation, interactive mouse/touch drag orbiting, and scroll zoom. 6. **Subtle Starfield Background**: A dense 2000-star particle field with additive blending and gentle stellar rotation. 7. **Glassmorphism HUD**: A polished floating control panel allowing customization of geometry detail, rotation speed, material gloss, light colors, wireframe mode, and theme presets (Cyberpunk, Solar Flare, Emerald, Monochrome).

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.
