— 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
A polished general Archimedes simulator with correct buoyancy physics, splash effects, and live readouts, but it implements none of the prompt-specific requirements: no crowns, no two-crown comparison, no vertical crown-lowering slider, no Heureka animation, and a dark (not light) background.
