✓ 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 via CSS rotate(180deg) which is a fragile fix and likely results in incorrect top=water/bottom=air mapping in most browsers; all other features are solidly implemented with correct physics (Au 19.3, Au+Ag 13.0, same 1000g mass, proportional displacement), animated ASCII water shimmer, splash particles, rising water level markers, and a Heureka overlay at full submersion.
