— 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
Generic single-object buoyancy demo with a horizontal slider and a bar-chart "force comparison" panel — no crowns, no gold/gilded comparison, no vertical slider, no per-crown mass/volume/density/displaced-water readouts, and no Heureka moment; almost none of the Archimedes-crown prompt requirements are met.
