— 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 crowns, no vertical slider controlling submersion, no water displacement or rising level — instead delivering a generic Archimedes sliders demo with horizontal density/volume controls and a falling rectangle.
