/* ============================================================
   Whitefield Projects - hub styling
   A DIRECTORY, not a brochure. The fleet's 159 microsites each
   sell one project; this one compares eighteen, so the design
   is editorial and data-forward rather than promotional:
   serif display type, a paper-toned ground, and a position bar
   on every figure that has a set to be measured against.

   Type is a SYSTEM stack on purpose. A web font would cost a
   request, a FOUT and a CLS risk on a page carrying eighteen
   images, and Georgia is already a real editorial serif on
   every platform we serve.

   Self-contained: a hub spans many developers, so it carries no
   builders/<id>.json brand tokens.
   Mobile-first, token-based, light + dark, WCAG AA.
