— 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 general Archimedes demo with solid physics and a Eureka animation, but completely misses the core prompt requirement: two crowns (pure gold vs. gilded), same-mass comparison, and a vertical submersion slider — instead providing horizontal sliders for density/size with no crown-specific scenario.
