— 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 single-body Archimedes simulator with correct physics and live readouts, but entirely misses the core prompt requirement: two crowns (pure gold vs. gilded) of equal mass and different density, vertical slider lowering them into water, rising water level, splash effects, and a Heureka animation.
