— 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 polished general-purpose Archimedes simulator with physics, drag interaction, and live readouts, but completely misses the brief: no two crowns, no same-mass/different-density comparison, no vertical slider controlling crown submersion, no rising water level, no Heureka moment, and uses a dark background — essentially a different demo.
