— 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 solid single-object Archimedes buoyancy simulator with correct physics and live readouts, but entirely misses the prompt's core requirement: two crowns (pure gold vs. gilded), a vertical immersion slider, fall/splash animations, rising water level, and the Heureka moment.
