✓ 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 (top label "☁️ Luft" / bottom "💧 Wasser" but slider value=0 at top means air which is correct conceptually, however the rotated range input maps slider thumb at top to min=0 which after rotation puts thumb visually at top = low value = air — actually direction may be correct; regardless, mass/volume/density values are static text, not live-updating data-value elements, missing the live readout requirement for those three fields.
