/* ==================================================
   SITE FOOTER
   Purpose:
   The large navigational footer — brand summary, link
   columns for services, technologies, industries and
   locations, contact block, social placeholders and the
   legal bar.

   The link columns are deliberately curated rather than
   exhaustive: dumping all ninety pages into every footer
   would bury the important ones and dilute internal link
   equity. Full catalogues live on the index pages.
