✓ 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 (label reads "↑ LUFT / WASSER ↓" but min=0 maps to crowns in air and max=1000 maps to submerged, which is correct behaviorally — however the rotated slider renders with top=submerged due to the CSS rotate(-90deg) transform flipping the visual direction); live mass value is static/not dynamically updated in the DOM; ASCII art approach is creative but limits visual fidelity of the water-rise and crown differentiation.
