— 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
This is a generic Archimedes buoyancy demo with a single rectangular block and horizontal depth/density sliders — it has no crowns, no vertical slider, no falling animation, no rising water level, and no Heureka moment, missing nearly every crown-specific requirement from the prompt.
