— 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
Polished general Archimedes demo with correct physics and live readouts, but it implements none of the prompt's specific requirements: no crowns, no crown-fall animation, no vertical immersion slider, no rising water level, no splash effects, no Heureka moment, and uses a dark background — it is essentially a different (though competent) educational tool.
