✓ 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 (value=0 maps to crowns at top/air, value=100 to submerged, but the HTML range default reads left=min meaning the rotated slider's visual top corresponds to max/water — functionally the drag direction feels reversed); no continuous fall animation (crowns jump/slide linearly without a timed drop sequence); physics values and dual-crown displacement logic are accurate and well-labeled.
