— 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 well-executed single-object Archimedes buoyancy simulator with correct physics and live values, but entirely misses the prompt's core requirements: no two crowns (pure gold vs. gilded), no vertical slider controlling submersion depth, no splash effects, no rising water level, no Heureka animation, and uses a dark background.
