— 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 wrong premise — implements a generic Archimedes buoyancy demo with material presets (wood/iron/gold/cork/ice) and a horizontal depth slider, with no crowns, no crown comparison, no vertical slider, no fall animation, no Heureka moment, and a dark background instead of light; the core prompt requirements are almost entirely absent.
