— 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
Entirely wrong concept — implements a generic buoyancy simulator with density/volume sliders instead of the two-crown (pure gold vs. gilded) Archimedes narrative; none of the required crown, fall animation, vertical immersion slider, rising water level, splash, or Heureka features are present.
