— 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 live physics values and a force graph, but entirely misses the core prompt requirement: two crowns (pure gold vs. gilded), same-mass comparison, vertical slider controlling fall, water-level rise, splash effects, and Heureka animation are all absent.
