— 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 buttons and materials but has no crowns, no vertical slider, no mass/volume/displaced-water live values, no splash/fall/heureka animations, and does not address the Archimedes crown narrative at all.
