— 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 well-crafted general Archimedes buoyancy simulator (density/fluid/size sliders, animated waves, bubbles, force arrows) but is fundamentally the wrong artifact — it shows no crowns, no vertical crown-dipping slider, no Heureka moment, no fall animation, no splash, no mass display, no pure-gold vs. gilded comparison, and uses a dark background with light text, missing nearly every prompt-specific requirement.
