/* ============================================================
   Shared site footer — SINGLE source of truth for <Footer />.
   Canonical 4-column layout (brand+credentials | links | links | contact).
   Linked LAST on every page so it overrides any stale per-page
   footer CSS still present in older page stylesheets.
   Source preview path for the pattern asset is relative (../../assets);
   the export build rewrites it to /assets via its own copy.
