— 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
Technically competent ASCII buoyancy simulator for a generic object, but entirely misses the brief: no crowns, no two-object comparison, no vertical slider controlling submersion, no falling animation, no splash, no water-level rise, and no Heureka moment.
