/* ==========================================================================
   Site footer
   --------------------------------------------------------------------------
   Loaded on every page, straight after header.css, so the two ends of the
   document share one visual language: the same glass surfaces, the same
   gradient hairlines, and the same amber line marker the nav uses.

   The theme's own footer rules live in main.css around .xb-footer-*. These
   override the parts that sat off-palette — flat #21232f social chips, plain
   text links with no hover affordance — without touching the layout.
   ========================================================================== */

/* --- Panel ---------------------------------------------------------------
   The panel is pulled 75px up over the footer artwork by main.css. Adding a
   hairline and a lit top edge stops it reading as a flat hole punched in the
   background image.
