— 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
Builds a solid general Archimedes demo with correct physics, live values, and water-level rise, but completely misses the prompt's core requirement: two crowns (pure gold vs. gilded), same-mass-different-density comparison, a vertical crown-lowering slider, fall/splash animations, and the Heureka moment.
