— 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 general Archimedes demo with material selector and decent physics, but entirely misses the prompt's core requirement: two crowns (pure gold vs. gilded), same-mass comparison, a vertical crown-dipping slider, splash effects, and a Heureka moment — it's a different app.
