— 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 ignores the Archimedes/crown prompt — implements a generic buoyancy demo with density/size sliders instead of two crowns (pure gold vs. gilded), no vertical slider, no fall animation, no Heureka moment, and uses a dark background; physics math is internally consistent but irrelevant to the spec.
