— 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 reimagined as a generic single-object buoyancy simulator with density/size/fluid sliders — none of the two-crown Archimedes story (Hiero's crown, gilded vs pure gold, vertical immersion slider, fall/splash animations) is present.
