— 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 explorer with correct physics formulas and live values, but entirely misses the prompt's core requirements: no two crowns, no vertical slider, no water-level rise, no splash effects, no Heureka animation, dark background violates light-bg spec, and the single horizontal "submersion depth" slider is not oriented correctly.
