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

Generic Archimedes buoyancy simulator with good physics and live readouts, but completely missing the two-crown (pure gold vs. gilded) narrative, vertical slider, fall/splash animations, rising water level, and Heureka moment that the prompt specifically required.
