✓ 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
ASCII-art text visualization with correct physics values and live readouts, but the slider is rotated via CSS (not a true vertical slider) and appears inverted (slider max triggers "fully submerged"), there is no smooth fall animation (crowns jump positions), and the displayed "volume" shows only displaced portion rather than total crown volume.
