— 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
Polished general Archimedes simulator with correct buoyancy physics and live force readouts, but fundamentally misses the brief: no two crowns, no crown-specific scenario, no falling animation, no splash, no rising water level, no vertical slider, no Heureka moment, and dark background violates light-bg requirement.
