— 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
Implements a generic Archimedes buoyancy simulator with correct physics formulas, but fundamentally ignores the prompt: no two crowns, no Heureka narrative, no falling animation, no splash, no rising water level, horizontal sliders only, and dark background with light text (inverted from requirement).
