— 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 misses the prompt: no two crowns, no Archimedes/Heureka narrative, no vertical crown-submersion slider — instead implements a generic single-object buoyancy simulator with density/fluid sliders and ASCII art.
