— 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 Archimedes/crown prompt — implements a generic buoyancy simulator with no crowns, no vertical crown-submersion slider, no gilded vs. pure-gold comparison, no fall animation, no splash, and no Heureka moment; the only overlap with the spec is correct Archimedes physics math and live displaced-volume display.
