— 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 single-object buoyancy demo with horizontal sliders and no crown context whatsoever — none of the core requirements (two crowns, same-mass/different-density, vertical slider, falling animation, water-level rise, splash, Heureka) are present.
