— 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 floating-ball Archimedes demo with density/size sliders, but completely misses the prompt's core requirements: no crowns, no vertical slider, no falling animation, no Heureka moment, and no two-crown comparison with same mass/different density.
