— 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 misses the brief: no crowns, no gold/gilded comparison, no vertical slider, no fall animation, no rising water level, no splash, no per-crown live values — it is a generic Archimedes explainer with a horizontal depth slider and ASCII art.
