✓ 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
Comprehensive ASCII-art implementation with correct physics (gold 19.3 g/cm³ vs gilded 13.0 g/cm³, same 1000 g mass, larger volume = more displacement), but the animated loop re-renders every 80 ms even without user input and splash effects are rudimentary character-substitutions rather than particle animations.
