— 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 floating ball and fluid/object density sliders — it has zero crown-specific content, no vertical submersion slider, no two-crown comparison, no water-level rise, no splash effects, and no Heureka animation, failing nearly every core requirement of the prompt.
