— 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
Competently built general Archimedes buoyancy simulator with correct physics and live readouts, but implements none of the required prompt features: no two crowns, no crown-vs-gilded comparison, no vertical slider controlling crown submersion depth, no fall animation, no splash effects, no rising water level, no Heureka moment, and uses a dark background.
