— 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
Completely off-brief: delivers a static ASCII art + text explainer about general buoyancy with no crowns, no slider, no animation, no live values, and no Archimedes/Heureka crown-comparison scenario whatsoever.
