— 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 well-crafted general Archimedes simulator with correct physics and animated waves, but it completely misses the prompt's core requirement: two crowns (pure gold vs. gilded), same-mass/different-density comparison, a vertical slider controlling crown submersion, fall/splash animations, and the "Heureka" moment.
