/* ============================================================
   FLYFORWARD BRAND THEME — shared design tokens & components
   Canonical source for colors, type scale, spacing, shadows and
   the handful of components (buttons, nav, cards, stats) that
   repeat across every page. See brand-guidelines.html for the
   documented palette this file implements.

   Usage: link this file on every page, AFTER the Google Fonts
   link and BEFORE the page's own <style> block. A page's inline
   <style> should only contain page-unique layout — not its own
   copy of these tokens or components.

   Dark-surface pages (brand-guidelines.html, member-portal/*)
   override just the color tokens in their own :root — the
   spacing/shadow/motion/radius scale and component rules here
   stay the same everywhere.
