Prompt for this run

Build a 3D solar-system visualization using the provided Three.js library. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. Use the provided `three.min.js` (global `THREE`) through a plain local script tag; the runner will inline it into the final artifact. Required behavior: - Show the Sun and all eight planets, with distinguishable colors, readable labels, and orbital paths against a procedural starfield. - Animate planets orbiting the Sun at different speeds. Use schematic sizes and distances for visibility; scientific scale accuracy is not required. Inner planets should generally orbit faster than outer planets. - Initially frame the complete system. Dragging orbits the camera around the Sun, and the mouse wheel changes camera distance within usable bounds. - Provide Pause/Resume and Reset view. Pause freezes planetary motion while leaving camera controls usable; Reset view restores the initial camera framing. - Generate materials and geometry procedurally. Only core global THREE is available; do not import additional controls or texture files. Verify: Inspect the initial planet labels and sample orbital motion. Orbit the camera and check that the system stays visible. Pause the simulation while adjusting the camera, then use Reset view and compare the initial framing.

Build index.html using the local three.min.js, and implement a custom orbit control (drag + wheel), labels (sprites using a canvas texture are procedural so no problem — or CSS overlays). Labels: use canvas-generated sprites. Starfield: THREE.Points with random positions.

Let me quickly check the three.min.js file and then write it.

Write index.html. Features:

- Sun (emissive sphere + point light), 8 planets with different colors and sizes, orbital radius as an approximate scale.
- Labels: canvas texture sprites that follow the planets.
- Orbital paths: THREE.LineLoop / RingGeometry or circles from points.
- Starfield: random Points on a sphere.
- Custom orbit control: spherical coordinates, clamp phi, clamp distance; wheel to zoom.
- Buttons: pause/resume, view reset.
- Animation: planet angle += speed * dt * paused.

Write it all in one go.

Wait — in a newer version of three, the default for useLegacyLights on PointLight intensity might make the lighting too dark, or it might be fine. Let me check the version and test it in the browser.

three r11x? "REVISION=e" — probably r118 or close to that. In r118, the PointLight decay=2 with physicallyCorrectLights=false should be fine... Actually, in older three, the default for decay is 1. Even if you set decay=2 without physicallyCorrectLights, the falloff works: light intensity / pow(distance, decay)? In legacy mode, when physicallyCorrectLights=false, the falloff for decay is... In legacy, when decay=0, attenuation = 1; otherwise it's a smooth curve. It should be fine, but the planets might get dark. I'll test it in the browser.

Looks good. Neptune's orbit (110) — is the outermost ring cut off? In the view the ring goes past the edge; Neptune's planet isn't visible? Neptune's orbit radius is 110, and the camera distance is 150. The outer orbit ring is partially off-screen (the ring at the bottom is clipped). The initial framing should include the entire system — the bottom of Neptune's orbit appears to be cut off at the bottom edge. Let's increase the initial distance to around 175, or decrease phi. The bottom edge is cut off: Neptune's orbit ring goes out past the bottom edge of the screen. Increase INITIAL.dist to 175.

Also, test drag, wheel, pause, and reset. First, adjust dist.

The outer orbits are clipped at the bottom edge. Let me widen the initial framing, then test interactions.

Note: In the first screenshot, Neptune wasn't visible (the label wasn't displayed) — the orbit at radius 110 was on the outside of the view. If I set the distance to 185, it should fit.

Now, the entire system including Neptune has become visible. Let's sample the orbital motion: take 2 screenshots at a short interval and check whether the planets have moved. The browser's "motion" action might capture frames. Let's click around to test dragging, and also test pause + reset.

Plan:
1. Check the motion (compare screenshots).
2. Drag the camera.
3. Click pause, drag the camera, then click reset and compare the framing.

Motion confirmed — planets are moving in different ways (Mercury is fast, Jupiter is slow). Next, test the camera drag.

Orbital motion is clearly visible at different speeds (inner planets move faster). Now testing camera drag.

Drag works — the camera orbits, and the system remains visible. Next, I'll test the wheel zoom, then pause + camera + reset.

Zoom in works. Next, test pause: click pause, confirm the planets are stopped, the camera is still draggable; then reset the view and compare the framing.

Click pause (button at approx. (63,68)).

Zoom works. Now clicking Pause and verifying planets freeze:

Paused (the button now shows "Resume" with active styling). While paused, I'll drag the camera, and then take two frames of motion to confirm the planets are frozen (the motion frames should show the same planet positions, but the camera may have moved due to the drag). Procedure: drag the camera → motion frame to confirm planets are frozen → click "Reset view" → compare with the initial framing.

Paused (button now "Resume"). Dragging camera while paused:

The camera is operable while paused. Next, I'll click "Reset View" and verify that the framing is the same as at the start.

Reset restored the initial framing (same angle/distance as the initial state. The planetary positions are different because time has advanced, but since it's paused it's frozen — no problem). Next, clicking resume to check whether the motion resumes.

Reset restored the initial framing. Verifying Resume:

Everything's working: after resuming, the planets are moving again (Venus/Earth moved slightly compared to when paused, and the button is back to "Pause"). Done. I'll report back.

All required behaviors verified. The final file is at `/tmp/job-ndQWxV/index.html`. **What I built** - Sun (emissive sphere + additive glow sprite + point light) and all 8 planets with distinguishable procedural colors/sizes, Saturn with a procedural ring - Canvas-texture sprite labels on the Sun and every planet (depth-test disabled so they stay readable), orbit path lines, and a 4,800-point procedural starfield on a large sphere - Orbits at schematic distances with speeds decreasing from Mercury (1.6×) to Neptune (0.18×) - Custom spherical camera controls (no extra libraries): drag to orbit, wheel to zoom (clamped 15–400 units), initial framing at distance 185 so Neptune's full orbit is on screen - Pause/Resume freezes only planetary motion; Reset view restores the exact initial camera angle/height/distance - Everything procedural; only dependency is the local `three.min.js` loaded via a plain script tag **What I checked in the browser** - Initial render: full system framed, all labels visible (Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune), no console errors - Motion: multi-frame capture showed inner planets visibly traveling while outer ones barely moved - Drag: camera orbited and the system stayed visible; wheel: zoomed in/out within bounds - Pause: button toggled to "Resume", planets froze while camera dragging still worked; Reset view restored the initial framing (identical angle/distance to the first screenshot); Resume restarted motion **Not explicitly verified**: exact wheel clamping at both hard bounds (15/400) and resize behavior after a window change — both are straightforward code paths but weren't exercised in the browser pass.
