— 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 buoyancy demo with a horizontal depth slider and object-type selector, but is entirely missing the two-crown (pure gold vs. gilded) scenario, vertical slider, fall animation, splash effects, Heureka moment, and mass live value — essentially none of the prompt's specific requirements.
