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 values for mass, volume, and density are static (hardcoded in HTML, never updated by JS), only displaced water updates dynamically; no fall animation — crowns jump position rather than animate; splash triggers mid-submersion rather than at water entry point.
