— Two crowns — Same mass, different density — Vertical slider — Slider works — Slider controls crowns — Slider direction correct — Full slider range — Fall animation ✓ Water displacement — Rising water level — Splash effects ✓ Physics correct — Live mass value ✓ Live volume value ✓ Live density value ✓ Live displaced water — Gilded displaces more — Heureka animation ✓ No external deps — Light bg / dark text ✓ Self-contained HTML
A well-polished general Archimedes buoyancy simulator, but it completely misses the prompt: no crowns, no two-object comparison, no vertical slider controlling crown submersion, no splash effects, no Heureka animation, and a dark (not light) background.
