✓ 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
Displaced water scales linearly with slider position rather than actual submerged crown volume, mass/volume/density values are static HTML (not live), no fall animation exists, and the water-rise pixel calculation is physically arbitrary rather than derived from Archimedes' principle.
