— 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
Implements a generic ASCII-art Archimedes buoyancy demo with a horizontal slider and no crowns, no two-object comparison, no water level rise, no splash effects, and no Heureka animation — missing virtually every crown-specific requirement from the prompt.
