— 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 floating cube and buttons — it implements none of the prompt's specific requirements: no crowns, no slider, no displaced-water live values, no Heureka animation, and no crown-specific physics.
