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

This is a well-built general Archimedes buoyancy demo but completely misses the prompt's core requirements: no two crowns, no vertical slider to dip them, no fall/Heureka animation, no rising water level, and no dark-theme inversion — it's a density/size parameter explorer, not the Archimedes crown story.
