— 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
Solid general Archimedes simulation with correct physics and live readouts, but completely misses the prompt's core requirements: no two crowns, no crown-specific scenario, no vertical slider, no fall/splash animation, no rising water level, and uses a dark (not light) background.
