**Inspecting files for index creation**

I realize I need to create an index, which means I should take a closer look at the files first. It seems like the initial step is to gather all the relevant data to ensure nothing is overlooked. I want to make sure I’m thorough, checking the contents to see how they can best be organized. Once I have a clear view, I can proceed with creating the index more effectively.
bash {"command":"pwd && ls -la && echo '---' && find . -maxdepth 1 -type f -printf '%f\n'"}

**Planning app development**

I need to create a polished app with three.js while ensuring I can satisfy requirements with a single file. I’m considering using custom controls for orbit dragging, and I need the canvas to be full screen. Implementation will involve adding resizing, stars, planets, orbits, and labels, with controls for pointer dragging and wheel actions. I think varied animation speeds will enhance the experience, plus maybe including a sun glow effect through sprites or emissive materials. I’ll also need to write an index.

Created `/tmp/ws/index.html` — a self-contained 3D solar system featuring: - Sun with glow effect - Eight orbiting planets with varied sizes and speeds - Saturn’s rings and Earth’s atmosphere - Orbit paths - Animated starfield - Drag-to-rotate camera controls - Scroll-to-zoom - Responsive overlay UI with live simulation time and camera distance - Inline CSS and JavaScript using the provided `three.min.js` only

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.
