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 general Archimedes buoyancy simulator (generic object in fluid) with correct physics and live readouts, but entirely misses the prompt's requirements: no crowns, no vertical crown-dipping slider, no gilded vs. pure-gold comparison, no Heureka animation, and uses a dark background instead of light.
