/* ============================================================
   Apex Realty AI — Design System
   Concept: the site is drawn as a set of numbered elevation
   sheets, the way an architect labels a blueprint set. Steel-blue
   corner ticks + mono coordinate tags carry that idea through
   every section instead of decorating it. One accent family
   (blueprint on paper, signal on ink) keeps the palette cool
   and systems-grade rather than "real estate warm."
