— 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 buoyancy demo with a density slider and water-level slider, but has none of the required crown-specific features: no two crowns, no same-mass/different-density comparison, no vertical submersion slider controlling crown positions, no fall/splash animations, no heureka moment, and physics values are only superficially modeled.
