✓ 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 maps to air, slider dragged DOWN = higher value = water, but HTML range input renders left→right when rotated −90°, making the visual top correspond to max=1000/water rather than air), and the crown-entering animation lacks a true fall/drop motion since both crowns move identically and linearly with no independent timing.
