— 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
Entirely wrong premise: this is a generic buoyancy simulator for arbitrary objects/fluids with horizontal sliders, no crowns at all, no Archimedes eureka narrative, no two-crown comparison, no vertical slider, no fall/splash animation, and uses a dark background — missing nearly every prompt-specific requirement.
