— 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 demo with correct floating/sinking physics and live readouts, but entirely misses the prompt's core requirements: no two crowns, no crown-lowering vertical slider, no fall/splash/heureka animations, no rising water level, and uses a dark theme instead of a light background.
