— 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 generic buoyancy demo with a single red cube and two tanks — entirely ignores the prompt's core requirement of two crowns (pure gold vs. gilded), vertical slider for submersion, Archimedes/Heureka narrative, and correct physics values.
