— 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 density/size sliders but entirely ignores the prompt's core requirement: two crowns (pure gold vs. gilded), same mass, falling animation, Heureka moment, and a vertical slider controlling crown descent — it's a fundamentally different demo.
