— 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 demo with cubes and a boat — no crowns, no crown comparison, no vertical immersion slider, no splash effects, no Heureka animation, and missing the core prompt requirement of comparing pure-gold vs. gilded crowns of equal mass.
