— 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
Completely misses the prompt's core requirements — no two crowns, no vertical slider controlling crown position, no Heureka animation, and uses a dark background; the general Archimedes physics visualizer with material/liquid dropdowns is a competent but entirely different application.
