— 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
Physically solid general Archimedes demo with good live readouts, but entirely misses the prompt's core requirements: no two crowns, no vertical slider controlling immersion, no fall/splash animations, no Heureka moment, and uses a dark background.
