/* Brackenridge Build
   ---------------------------------------------------------------------------
   Follows the Collins Construction reference: full-bleed photography carrying
   the colour, a white/light-grey alternation between panels, one blue for
   action, an ebony footer, and a spectrum rule that appears once under the
   hero. Type is measured off that build — 50/26.5/21.5/17.5/14/12 on a 1.23
   scale, Inter for headings, a geometric humanist sans for everything else.

   Colour tokens are declared per surface rather than per component, which is
   the rule carried forward from the rest of this series.
