— 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
Implements a generic Archimedes buoyancy demo with a generic object (not two crowns), uses horizontal density/size sliders instead of a vertical slider controlling crown descent, has no pure-gold vs. gilded-crown comparison, dark background violates light-bg requirement, and misses nearly every crown-specific feature requested.
