— 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 live values, but completely misses the core prompt requirement: two crowns (pure gold vs. gilded), same-mass comparison, vertical slider, falling animation, rising water level, splash effects, and Heureka moment.
