   Loaded after triways-core / triways-hub / triways-article. Every rule is
   scoped under body.page-about. Uses the core --hb-* tokens (the same ones
   the .ex-* components use); the additions are defined once below.
   The DNA is copied from the approved /exclusive/ components (.ex-hero,
   .ex-bleed, .ex-faq, .ex-enquiry) into .ab-* equivalents, so
   triways-exclusive.css stays untouched.
