iPad support — UnitX now has a proper split-view layout on iPad, in both
portrait and landscape, instead of a stretched-up phone screen.

New here? A short setup flow now asks which categories you convert most and
puts them first.

Also fixed:
• "5 million", "2 crore", and "1.5 lakh" now scale correctly, including with a
  currency symbol in front (¥1 million, ₹1 billion)
• Fuel-economy conversions no longer break on a zero value
• History entries now show the correct date near midnight
• Opening the manual converter from a smart result carries the right units
  across every time
• Dark mode now survives a relaunch
• Favorites and recents reach the Watch on first sync instead of arriving empty
