— 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 explainer with ASCII art and toggle buttons, but is entirely missing the two-crown scenario, vertical slider, all live value readouts, fall/splash/rising-water animations, and the Heureka moment — essentially none of the prompt's specific requirements are met.
