✓ 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 (min=0 at top maps crowns to air correctly by coincidence of crownStartY logic, but labels show "↑ Luft / ↓ Wasser" while HTML default range increases left-to-right when rotated -90°, making top of slider = high value = submerged — direction bug); mass, volume, and density values are static HTML (not live JS-updated elements), only displaced water and buoyancy update dynamically.
