— 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 competent generic Archimedes buoyancy simulator with correct physics and live values, but fundamentally ignores the prompt: no crowns, no Archimedes/Heureka narrative, no vertical slider controlling submersion depth, no fall animation, no splash, no rising water level, and uses a dark background instead of light.
