/* =========================================================================
   BOSSMAN — BIM & REVIT-BASED FACADE DESIGN
   Page-scoped stylesheet   |   architectural-consulting.php
   -------------------------------------------------------------------------
   Extends the Antra theme. Inherits typography (Cal Sans / Golos Text),
   spacing utilities (pt-130 / pb-130 / pb-80), grid (.container-2),
   buttons (.tl-primary-btn) and reveal classes (.fade-wrapper / .fade-top)
   from main.css. Nothing here overrides global theme rules — every
   selector is namespaced with the `bf-` prefix.
