— 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 general Archimedes buoyancy simulator with correct physics and smooth animation, but is entirely missing the two-crown (pure gold vs. gilded) Archimedes narrative, vertical immersion slider, fall/splash animations, and Heureka moment — the core requirements of the prompt.
