— 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
This is a well-built general Archimedes buoyancy demo but completely misses the prompt's core requirements: no two crowns, no vertical slider to dip them, no fall/Heureka animation, no rising water level, and no dark-theme inversion — it's a density/size parameter explorer, not the Archimedes crown story.
