✓ 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
Buoyancy force unit conversion is wrong (multiplied by 1000 twice, yielding values in µN-scale labelled as mN), and both crowns submerge identically rather than showing independent depth/fraction behavior; water rise differential is present but the force readout is physically nonsensical.
