— 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 ignores the core prompt (two crowns, Archimedes/Hiero story, vertical slider, falling animation, splash, Heureka moment); instead delivers a generic material-density sandbox with a horizontal depth slider and ASCII art rendering on a dark background.
