/* --------------------------------------------------------------------------
   BRAND COLOURS - two-layer system. OFFICIAL EAG Travel palette, taken from
   the July 2026 brand guidelines (EAG-Travel-Visual-Identity-July-2026.pdf).
   Do NOT alter these values or invent new brand colours.
     Layer 1  Swatches: raw brand colours, defined once (hex + rgb twin).
     Layer 2  Roles:    semantic pointers into the swatches.
   To RECOLOUR : edit a swatch hex below.
   To REORDER  : re-point a role var, e.g. make teal the primary:
                   --brand-primary: var(--eag-teal);
                 (also move its --brand-primary-rgb twin to --eag-teal-rgb).
   Everything else - Bootstrap --bs-* overrides, component styles, templates -
   references ROLE vars only, never a swatch or a raw hex.
