— 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
Technically polished general Archimedes simulator with correct physics and live readouts, but fundamentally misses the prompt: no two crowns, no same-mass/different-density comparison, no vertical fall-control slider, no Heureka animation, and dark background violates light-bg requirement.
