— 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
A polished generic Archimedes simulator with correct floating/sinking physics and live readouts, but entirely misses the brief: no crowns (pure gold vs. gilded), no vertical slider controlling crown descent, no fall animation, no splash, no Heureka moment, and uses a dark background throughout.
