— 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
Visually polished generic Archimedes buoyancy simulator (single sphere, density/fluid sliders) — implements none of the required Archimedes-crown narrative: no two crowns, no same-mass/different-density setup, no vertical dip slider, no fall/splash animation, no Heureka moment, and dark background violates light-bg requirement.
