— 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
Implements a polished general Archimedes simulator with correct physics and live values, but is entirely the wrong demo — it shows a single configurable block (not two crowns), has no vertical immersion slider, no fall/splash animation, no rising water level, no gilded vs. pure-gold comparison, and no Heureka moment.
