— 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 polished general Archimedes simulator (density/volume sliders, multi-fluid support, force arrows) but fundamentally misses the entire prompt: no two crowns, no crown-drop animation, no vertical immersion slider, no Eureka moment, and dark background instead of light.
