/* Fata design system.
   Brand: navy #233E7D, teal #56AEAB (sampled from the logo).
   Type:  Noto Kufi Arabic for Arabic, Century Gothic for Latin with
          Questrial as the free geometric stand-in.
   Layout uses CSS logical properties everywhere (margin-inline,
   inset-inline, text-align:start) so RTL and LTR share one stylesheet. */
