— 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 prompt's core requirements (two crowns, gold vs. gilded, Archimedes bath story, vertical slider controlling submersion) and instead implements a generic ASCII buoyancy scene switcher with no crowns, no density/mass/displaced-water readouts, no animation, and a horizontal slider that doesn't map to crown depth.
