— 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
Competent general Archimedes simulator with correct physics and live readouts, but fundamentally off-topic: shows one generic object (not two crowns), has no vertical slider controlling submersion depth, no crown-fall/splash animation, no Heureka moment, and uses a dark background — missing nearly every crown-specific requirement.
