/* ==========================================================================
   RVKS — rvx-footer
   Self-contained, namespaced site footer. Requires NO Bootstrap grid/JS, no
   jQuery, no yit-* asset, no FontAwesome (icons are inline SVG). Zero JS.

   Scope discipline: every rule below is scoped to .rvx-footer. Nothing leaks
   outside it — no bare element selectors, no utility classes, no overrides of
   anything the rest of the page owns.

   Palette + type match css/rvx-header.css so header and footer read as one
   system. Tokens are re-declared locally (not inherited) so this file can be
   dropped onto a page that does not load the header component.
