/* ==========================================================================
   IbnKhafagah for Development — site stylesheet

   Hand-written, no build step: the deployment target is ordinary PHP hosting,
   so the CSS ships as-is and needs no npm on the server.

   The palette is dark only. The brand mark is a glowing blue on near-black and
   has no light-background lockup, so a light theme would need different artwork
   before it could look right.

   Layout is logical-property based (inline-start/end, margin-inline) so the same
   rules serve both the Arabic RTL and English LTR renderings.
