/*
  Mashq stylesheet.

  - Phone first: base styles are for small screens; wider screens add to them.
  - No web fonts: the phone's own fonts load instantly and cost no data.
  - "inline" / "block" properties (margin-inline-start etc.) instead of
    left/right, so the layout flips correctly for right-to-left Urdu later.
