— 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 and live readouts, but completely misses the brief: no two crowns, no crown-specific mass/density scenario, no vertical slider for lowering into water, no fall or splash animation, no Heureka moment, and uses a dark background instead of light.
