— 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 Archimedes drag demo with wood/stone instead of the required two crowns (pure gold vs. gilded), has no vertical slider, no crown-specific physics, no live mass/volume/density/displaced-water readouts, and no Heureka animation — nearly every core requirement is absent.
