— 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 general Archimedes buoyancy simulator with correct physics and decent visuals, but entirely misses the prompt's core requirements: no two crowns (pure gold vs. gilded), no vertical immersion slider, no fall/splash animation, no Heureka moment, and uses a dark background instead of light.
