/* =====================================================================
   STYLE.CSS  —  layout & components. This reads the variables from
   theme.css. You normally DON'T need to edit this file to restyle the
   site — change theme.css instead. Edit here only to change structure.

   Uses CSS logical properties (margin-inline, padding-block, inset-*)
   everywhere, so the Arabic RTL pages work from the same stylesheet
   with no separate right-to-left file.
