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

Comprehensive SVG-based implementation with correct physics (1000g same mass, 51.8 vs 76.9 cm³), iterative water-level convergence, splash/bubble effects, and Heureka animation, but lacks a true fall animation (crowns teleport rather than animate on drop) and mass/density values in data panels are static rather than dynamically computed.
