— 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
This is a well-built general Archimedes buoyancy simulator with correct physics and polished dark-themed UI, but it entirely misses the prompt's requirements: no crowns, no two-crown comparison, no vertical slider controlling submersion, no fall/splash animations, no heureka moment, and uses dark background with light text instead of the specified light background.
