✓ 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 to air, max=100 at bottom maps to water, but the vertical slider in most browsers renders min at bottom and max at top, making top=water/bottom=air unless corrected); physics values are correct (Gold 19.3 g/cm³, mix 12.8 g/cm³, same 1000g mass), ASCII art is charming but crown fall animation is discretized into coarse char-row steps with no smooth interpolation.
