— 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
Implements a well-polished general Archimedes demo with correct physics (buoyancy ratio, force arrows, status), but completely misses the prompt's core requirements: no two crowns, no vertical immersion slider, no fall/splash animation, no Heureka moment, and uses a dark background.
