✓ 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
Slider direction is inverted (value=0/top maps to crowns in air, but HTML range input renders 0 at the bottom visually when rotated -90°, making the physical drag direction counterintuitive); mass, volume, and density panels show static values only — only displaced water updates live, leaving three of four required live metrics unimplemented.
