— 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 misses the prompt's core requirement — no two crowns, no vertical immersion slider, no fall/splash animation, no Heureka moment; instead delivers a generic single-object Archimedes demo with density/size/fluid sliders.
