✓ 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 labeled "Luft", max=100 at bottom labeled "Wasser", but HTML range inputs render with low value at top visually via CSS rotation, making direction ambiguous/potentially confusing); otherwise a very complete, physics-accurate, visually polished implementation with proper particles, bubbles, rising water level, and a full Heureka overlay.
