I’ll inspect the workspace, then build the lamp in one self-contained HTML file. I’ll check the animation and layout at desktop and phone sizes.

The script parses, and the lamp’s proportions place its base on the desk at both target sizes. This sandbox blocks browser screenshots, so I’m running a direct simulation check for blob merging and splitting and for the switch’s on/off state.

The simulation check shows repeated merges and splits, and the blobs settle after the lamp is switched off. I’m doing one final single-file check and removing the temporary verification files.

Built the lava lamp in [index.html]([workspace]/index.html). It’s a single file with no external requests, a phone-sized layout, temperature-driven wax that rises, sinks, merges and splits, and an on/off switch.

I verified the script and simulated the wax and switch behavior. The animation is designed for 60 fps, but I couldn’t measure browser frame rate in this environment.
