— 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 solid general Archimedes simulator with correct physics, bubble effects, and live values, but entirely misses the prompt's core requirements: no two crowns, no vertical slider controlling submersion, no same-mass/different-density crown comparison, no Heureka animation, and dark background violates the light-bg spec.
