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

Mass/volume/density values are static hardcoded text (not live-updating elements), so only displaced water is truly "live"; slider is custom SVG-drag with correct direction and full range but lacks a native range input.
