— 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
Physically sound general Archimedes demo with good calculations, but completely misses the brief: no crowns (pure gold vs. gilded), no vertical slider controlling fall into water, no splash, no rising water level, no heureka moment — it's a generic floating-body simulator on a dark background.
