— 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 demo with horizontal sliders and a single floating block — completely missing the two-crown Archimedes narrative, vertical slider, fall animation, rising water level, splash effects, and Heureka moment.
