/* ==========================================================================
   ANF brand-page chrome
   --------------------------------------------------------------------------
   The ONLY shared styling across brand pages. It covers the ANF top bar and
   footer so a visitor always knows where they are and how to get back, while
   leaving the entire page body free to look like the brand's own site.

   Every colour here reads from a variable the page sets, so the chrome adapts
   to a light or dark brand palette. A page only needs to define these on
   :root (all optional - sensible ANF defaults apply):

     --chrome-bg          bar/footer background
     --chrome-fg          bar/footer text
     --chrome-fg-muted    secondary text
     --chrome-border      hairline
     --chrome-accent      hover / active colour
   ========================================================================== */

  --chrome-bg: #0a1628;
  --chrome-fg: #ffffff;
  --chrome-fg-muted: rgba(255, 255, 255, 0.62);
  --chrome-border: rgba(255, 255, 255, 0.14);
