— 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
Competent ASCII Archimedes sandbox with correct physics and live values, but entirely misses the brief: no two crowns, no crown-comparison scenario, no vertical crown-lowering slider, no fall/splash animations, and uses dark background with light text.
