✓ 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
Fully featured, physics-correct implementation with elegant SVG crown art, iterative immersion refinement, animated splash/heureka, and live panel values — minor weakness is the pixel-to-cm³ water scale being arbitrary rather than geometrically derived from container dimensions.
