/* ═══════════════════════════════════════════════════════════════
   GPB Footer (footer.php) + back-to-top button
   Loaded after the RedStar theme so it wins over theme_style.css /
   responsive.css .page-footer rules. The .page-footer class is kept
   for the theme's sidebar offsets and layout.js height maths.

   Floating buttons share one right-hand axis:
     Buddy FAB      56px, right 20px, bottom 20px  (inc/buddy-widget.php)
     Back to top    44px, centred on the same axis, 12px above Buddy
   The footer keeps a right-hand gutter so neither button covers it.
