— 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 general Archimedes buoyancy simulator (single object in fluid with material/liquid dropdowns) — it does not implement the two-crown Archimedes story at all: no crowns, no fall animation, no vertical crown-dipping slider, no heureka moment, and no gilded-vs-pure-gold comparison.
