— 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 simulator with correct physics and a decent dark UI, but completely misses the prompt's core requirements: no two crowns (pure gold vs. gilded), no vertical submersion slider, no fall animation, no splash effects, no Heureka moment, and the background is dark not light.
