— 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
This is a competent general Archimedes buoyancy simulator, but it completely misses the prompt's core requirement: two crowns (pure gold vs. gilded), same-mass comparison, a vertical immersion slider, fall animation, splash effects, and the Heureka moment — none of these are present.
