— 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 fundamentally misses the prompt's core requirement: two crowns (pure gold vs. gilded), same-mass constraint, vertical immersion slider, fall/splash animations, and the Heureka moment — it's a generic density explorer, not the Archimedes crown experiment.
