— 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 general Archimedes buoyancy demo with horizontal density/size sliders and no crowns — it completely misses the two-crown (pure gold vs. gilded), vertical slider, falling animation, rising water level, splash, and Heureka requirements of the prompt.
