— 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 generic Archimedes buoyancy simulator with a single generic block and horizontal sliders — it implements none of the required crown-specific features: no two crowns, no Hieron's crown narrative, no vertical slider, no fall animation, no rising water level, no splash effects, and no Heureka moment.
