/* ============================================================
   SEMIOTECHS — one flowing page.

   The restraint is the design. A knowledge company's site that shouts is
   arguing against itself, so: one accent, a lot of air, a display serif
   against a quiet sans, and rules instead of boxes wherever a box is not
   load-bearing.

   Three languages share this sheet. Arabic is not a translation laid over a
   Latin layout — the document direction flips, and every edge that matters
   is written with logical properties (inline-start/end, margin-inline) so it
   flips with it.
