Using the pre-provided three.min.js (global THREE), render an interactive 3D Rubik's Cube with clickable face rotations, orbit-drag camera, and a scramble button.
thinking
The user wants me to build a 3D Rubik's Cube using three.min.js (already present in the directory) in a single index.html file. Let me first check what's available, then build it. Key features needed: 1. Interactive 3D Rubik's Cube with proper colors 2. Clickable face rotations (click on faces to rotate them) 3. Orbit-drag camera (orbit controls - I'll need to implement this manually since we can only use three.min.js) 4. Scramble button 5. All self-contained in one HTML file Let me first verify three.min.js exists.
{"command":"ls /tmp/ws/three.min.js"}/tmp/ws/three.min.js
thinking
Good, it exists. Now let me build the full Rubik's Cube app. I'll implement orbit controls manually (no OrbitControls addon), use raycasting for face clicks, and build a proper 3x3 cube with standard colors.

Let me review the code and fix a few things. The orbit controls need to track currentRadius properly, and I should make sure the click-to-rotate logic works well. Let me also simplify and clean up some of the code for better reliability.
Now let me refine the implementation with more robust click detection and cleaner controls:

Let me verify the file is there and looks correct.

thinking
The file is created. Let me also verify that three.min.js is still present and check for any obvious issues in the code by reading a quick portion of it.

thinking
Both files are present. Let me do a final review of the code to make sure there aren't any issues, particularly around the click-to-rotate direction mapping and the reset logic (disposal might cause issues if geometries are shared).
Let me clean up one small issue — `BoxGeometry` is shared across cubies so disposing it once would break others:
{"path":"/tmp/ws/index.html","edits":[{"oldText":" document.getElementById('resetBtn').addEventListener('click', () => {\n if (animatingSuccessfully replaced 1 block(s) in /tmp/ws/index.html.
thinking
Good. Now let me verify the final file one more time to make sure everything looks correct, then I'm done.

Good. The file looks correct. Let me verify the structure is complete by checking the end of the file.

thinking
The file is complete and well-structured. Let me provide a summary for the user.
Done. **`/tmp/ws/index.html`** is ready — 395 lines, fully self-contained with: | Feature | Implementation | |---|---| | **3D Rubik's Cube** | 27 cubies with official colors (Red/Orange/White/Yellow/Green/Blue) + dark inner faces + edge wireframes | | **Click-to-Rotate** | Raycasting on face clicks → detects which face was clicked and normal → picks perpendicular rotation axis → smooth ease-out cubic animation | | **Orbit Camera** | Custom pointer-drag orbit control (left-mouse drag rotates around cube center) | | **Zoom** | Scroll wheel adjusts camera distance (clamped 3.5–15 units) | | **Scramble** | Random 20-move Singmaster sequence (`R/L/U/D/F/B` with ``, `'`, `2`) played back sequentially with animation queue | | **Reset** | Rebuilds the cube from scratch to solved state | **No external dependencies** — only `three.min.js` loaded locally via `<script src>`.

RUN
EVALUATION
3D Rubik's Cube renders and orbit-drag/wheel zoom works, but drag rotated view to a top-down white-only angle, no face rotation visible.

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.
