— 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
Entirely wrong artifact — implements a generic Archimedes buoyancy explainer with three static SVG scenes (swim/sink/float) and simple bounce animations, with no crowns, no slider, no live values, no water-level rise, no splash effects, and no Heureka moment; essentially none of the specified requirements are met.
