/* =====================================================================
   AY STRUCTURAL v2 — dark design system
   Source of truth: Claude Design handoff (design_handoff_ay_site).
   Loads AFTER ay-brand.css / site.css / score.css and migrates the whole
   site to the approved dark direction (ink-surface, hairline bento,
   mono CTAs, Fraunces display). Two layers:
     1. Token flip — legacy components inherit dark surfaces via vars.
     2. New ay-* components used by the rebuilt pages.
