✓ 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
Comprehensive ASCII implementation checks every box, but water-rise is cosmetically rounded to integer grid rows (losing sub-row precision) and the splash trigger logic is fragile — the heureka overlay fires correctly and the physics values (19.3/10.5 g/cm³, 51.8/95.2 cm³) are accurate throughout.
