— 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 material/fluid density sliders and animated bubbles, but entirely ignores the prompt: no two crowns, no vertical immersion slider, no fall/splash animation, no Heureka moment, dark background violates light-bg requirement, and the physics uses an arbitrary normalized volume rather than real SI values.
