— 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
A polished general Archimedes buoyancy demo with smooth animation and correct physics, but it completely misses the prompt's core requirements: no two crowns (gold vs. gilded), no vertical slider controlling crown immersion depth, no fall animation, no splash effects, no Heureka moment, and uses a dark background — it is essentially a different demo.
