— 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 a single generic object and material/size/fluid-density controls, but entirely misses the prompt's core requirement: two crowns (pure gold vs. gilded), same mass, vertical fall-into-water slider, crown-specific physics, Heureka animation, splash effects, and light background.
