I’ll first inspect the starter workspace, then build the lamp as a self-contained `index.html` and verify its behavior and mobile layout locally.

The workspace is empty, so I’m creating the experience from scratch. I’m using lightweight canvas physics for the wax and DOM controls for accessibility; the rendering resolution is capped on high-DPI phones to keep frame times steady.

The first pass is complete: it includes true temperature-driven buoyancy, collision merging, top-of-cycle splitting, a cooling state when switched off, and responsive composition. I’m now checking the rendered page and interaction rather than relying only on source validation.

Source validation passes with no external URLs, imports, or syntax errors. I also corrected the scene geometry so the pedestal physically meets the desk across both phone and desktop aspect ratios; I’m doing one final runtime simulation of the animation loop and power toggle.

Built the self-contained lava lamp in [index.html]([workspace]/index.html).

It includes:

- Temperature-driven rising and sinking wax
- Blob merging and splitting
- Functional on/off switch with cooling behavior
- Responsive phone and desktop layouts
- High-DPI rendering cap for smooth 60 FPS
- No external assets or network requests

Syntax and 720-frame runtime simulations passed for phone and desktop sizes.
