✓ 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 crowns to air which is correct in logic, but the CSS rotation trick means the visual top of the slider corresponds to value=0/air and bottom to value=100/water — actually let me re-examine: the slider has min=0 value=0 and is CSS-rotated -90deg, so visually the left becomes top; slider_direction_correct is ambiguous but the rotated horizontal slider's "top" visually is the max end, making value=100 at top = fully submerged, which is inverted); no fall animation (crowns teleport linearly rather than dropping with gravity/easing); splash and heureka are well-implemented but the submerged-fraction calculation ignores the rising water surface, slightly underreporting displacement.
