— 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 single generic cube (not crowns), a horizontal depth slider (not vertical), no two-crown comparison, no mass/volume/displaced-water live values, no fall animation, no splash effects, and no Heureka moment — virtually none of the crown-specific prompt requirements are met.
