✓ 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
Impressively complete ASCII-art implementation with all required features; slider direction is correctly handled via explicit inversion (100-rawVal), but immersion percentage is tied purely to slider t rather than computed from crown-in-water geometry, so both crowns show identical immersion % instead of reflecting their different volumes.
