— 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 generic buoyancy visualizer (single sphere, volume/density sliders) with no crowns, no vertical slider, no fall animation, no splash, and no Heureka moment — missing nearly every crown-specific requirement from the prompt.
