— 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 Archimedes crown narrative: no two crowns, no crown-specific physics, no vertical submersion slider controlling crown depth, no fall/splash animation, no Heureka moment, and uses dark background — the demo is a generic buoyancy sandbox that misses nearly every required feature.
