— 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
Completely misses the core prompt requirement of two crowns (pure gold vs. gilded) with a vertical slider controlling immersion; instead implements a generic Archimedes demo with material selector buttons, horizontal sliders, and a button-triggered animation.
