— 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 ignores the crown/Archimedes-crown-comparison prompt — implements a generic buoyancy demo with a cube, buttons instead of a slider, no two crowns, no mass/volume/density readouts, and no Heureka animation.
