/* ==========================================================================
   FairTech Header Redesign
   Visual layer only — every selector below targets markup/classes that are
   used exclusively inside header.php (verified via repo-wide grep), so
   nothing here touches product pages, checkout, blog, or the admin panel.
   Loaded after style-min.css AND bootstrap.min.css so it reliably wins the
   cascade for shared classes like .offcanvas / .modal / .dropdown-menu on
   the specific header components scoped by ID below.
   Depends on tokens defined in design-system.css.
