— 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 simulator (single generic body, material buttons, fluid density slider) — it does not implement the required two-crown Archimedes narrative, vertical submersion slider, crown fall/splash animation, water-level rise, or Heureka moment in any form.
