✓ 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
Solid ASCII-art implementation with correct Archimedes physics (gold 19.3 g/cm³, gilded ~13.1 g/cm³, same 1000g mass), live data panel, splash effects, and Heureka animation, but the slider has a duplicate 'input' listener (second one overwrites the first's splash logic), there is no discrete fall animation (crowns move linearly with the slider rather than falling), and the ASCII rendering is functional but visually constrained.
