— 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
Completely wrong premise: this is a generic Archimedes buoyancy simulator with a single configurable object and horizontal sliders, not the required two-crown (pure gold vs. gilded) Archimedes story demo with a vertical slider, falling animation, water-level rise, splash effects, or Heureka moment.
