— 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
Completely wrong demo — implements a generic Archimedes buoyancy simulator with one sphere and density/fluid sliders, with no crowns, no crown-specific slider, no gilded vs. pure-gold comparison, no Heureka animation, and a dark (not light) background.
