— 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 competent general Archimedes buoyancy simulator with correct physics and live values, but is entirely off-prompt: no two crowns, no vertical immersion slider, no fall/splash animation, no Heureka moment, and uses a dark background — the core requirements are unmet.
