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

Implements a solid generic Archimedes buoyancy simulator with correct physics and live readouts, but completely misses the prompt's core requirements: no two crowns, no crown-specific slider controlling immersion depth, no fall animation, no splash, no rising water level, no Heureka moment, and dark background instead of light.
