— 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 misses the Archimedes crown narrative — no two crowns, no vertical crown-submersion slider, no fall/splash animation, no heureka moment; instead implements a generic Archimedes buoyancy demo with horizontal density/size sliders and dark background, satisfying almost none of the specific prompt requirements.
