— 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
Competent general Archimedes demo (single generic object, density/fluid sliders, correct buoyancy math) but completely misses the brief: no two crowns, no same-mass-different-density setup, no vertical fall-control slider, no rising water level, no splash, no Heureka moment, and uses a dark theme.
