/* ============================================================
   COMPONENT: Footer (Global)
   FILE: assets/css/footer.css
   Phase: Stage 6 (Final Master Blueprint Roadmap V3, §8).
   Depends on: tokens.css, base.css, buttons.css, surfaces.css
   (loaded before this file — Phase 1.0 §6 fixed order). Owns
   only .site-footer* selectors; reuses .btn/.icon-btn/.container/
   .surface--gradient from their owning stylesheets rather than
   redefining them.

   Bilingual/RTL: every rule below uses logical properties
   (margin-inline, padding-inline, text-align: start, inset-inline)
   instead of left/right, so this section mirrors correctly under
   dir="rtl" with no component-level override needed — direction-
   sensitive exceptions (icon mirroring, back-to-top offset) are
   handled centrally in rtl.css (Stage 6.5), not here.
