— 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 well-physics'd single-sphere buoyancy simulator with horizontal density/gravity sliders, but is entirely missing the two-crown Archimedes narrative, any vertical submersion slider, crown fall/splash animations, rising water level, and the Heureka moment — essentially none of the prompt's core requirements are present.
