— 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
This is a generic Archimedes buoyancy demo with a single red cube, no crowns, no slider, no per-crown physics values, and no Heureka moment — it satisfies almost none of the prompt's specific requirements.
