— 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 demo with a sphere and fluid/material sliders, but it completely misses the prompt: no crowns, no crown-lowering vertical slider, no same-mass/different-density pair, no fall animation, no splash, no rising water level, no Heureka moment, and uses a dark background — essentially the wrong simulation was built.
