✓ 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
Live mass, volume, and density values are static text hardcoded in SVG rather than dynamically updating elements, so only displaced-water updates live; slider is a custom SVG drag handle (no native range input) that works but lacks the precision and accessibility of a true vertical slider.
