— 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 general Archimedes buoyancy simulator (generic object in fluid) with correct physics and live readouts, but entirely misses the prompt's requirements: no crowns, no vertical crown-dipping slider, no gilded vs. pure-gold comparison, no Heureka animation, and uses a dark background instead of light.
