— 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 solid general Archimedes demo with correct physics, live values, and a "Heureka" animation, but fundamentally misses the prompt's core requirement: two crowns (pure gold vs. gilded) with a vertical slider controlling submersion depth — instead showing a single selectable material with a horizontal depth slider.
