✓ 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
Physics values are correct (gold 19.3 g/cm³, alloy 13.0 g/cm³, same 1000 g mass, different volumes), water rise differential is clearly visible, but mass/volume/density are static display values rather than live-updating, and the ASCII-art rendering is functional but visually rudimentary.
