I’ll build the lamp directly in the workspace as a self-contained `index.html`, then open it locally to check the layout and interaction.

add [workspace]/index.html

The page is in place: it has a responsive lamp scene, canvas-based wax simulation, glow and glass shading, plus an accessible on/off switch. I’m doing a quick syntax and behavior sanity check now.

- Rising, cooling, merging, and splitting wax blobs
- Glass lamp, glow, desk, and ambient room styling
- Accessible on/off switch with cooling behavior
- No external assets or network requests
- JavaScript syntax and self-contained checks passed
