— 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
Implements a generic Archimedes buoyancy demo with a single draggable cube — no crowns, no crown-fall animation, no splash effects, no rising water level from displacement, and the slider is horizontal (not vertical), making it fundamentally non-compliant with the prompt's core requirements.
