— 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 general Archimedes buoyancy simulator with correct physics and polished dark-theme SVG rendering, but completely misses the brief: no two crowns, no crown-submersion vertical slider, no fall/splash/heureka animations, no rising water level, and uses a dark background instead of light.
