— 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 ASCII-art Archimedes demo with correct physics and live values, but fundamentally wrong subject matter — implements a generic object-in-water simulator with selectable materials, not the two-crown (pure gold vs. gilded) Archimedes story at all, missing the core requirement entirely.
