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 well-physics'd single-sphere buoyancy simulator with horizontal density/gravity sliders, but is entirely missing the two-crown Archimedes narrative, any vertical submersion slider, crown fall/splash animations, rising water level, and the Heureka moment — essentially none of the prompt's core requirements are present.
