— 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
Competent generic Archimedes simulator with correct physics and animated water/bubbles, but fundamentally ignores the prompt: no two crowns, no vertical crown-dipping slider, no splash/fall animation, no Heureka moment, no gilded-vs-pure-gold comparison, and uses a dark background.
