✓ 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
Slider is horizontal (not vertical as specified), ASCII/pre-canvas rendering is rudimentary with minimal crown differentiation, but physics values (gold 19.3 g/cm³, gilded 8.0 g/cm³, same 1000 g mass) and displacement logic are correct.
