/* ==========================================================================
   SITE FOOTER
   Loaded last, sitewide.

   Two earlier layers have to be outranked here, which is why !important
   appears on the colour declarations and nowhere else:

   1. main.css:4422, a "Sticky Footer Layout Fix" block that repaints the
      whole footer with !important.
   2. main.css:4487+, a `[data-theme="dark"] .site-footer …` set that is more
      specific than anything scoped to `.site-footer` alone.

   Everything below is driven by the token block: the component rules name
   --ft-* and never a literal colour, so light and dark are two short lists of
   values rather than two copies of the stylesheet.

   Markup is untouched. footer.php carries the region-aware menu logic
   (data-us-href / data-au-order / data-region-only) that region-switch.js
   rewrites at runtime, and none of that should be disturbed for a restyle.
