— 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 solid general Archimedes demo with correct physics and live values, but completely misses the brief: no two crowns, no crown-lowering vertical slider, no fall animation, no Heureka moment, dark background instead of light, and the density/size sliders are horizontal and control an abstract object rather than the specified gold vs. gilded crown scenario.
