— 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 generic Archimedes buoyancy simulator with solid physics and live readouts, but completely ignores the prompt: no two crowns, no crown-specific scenario, no vertical immersion slider, no fall/splash animation, dark background violates light-bg requirement, and no Heureka moment.
