/* ===========================================================================
   Sisters Arabic - global header (inner pages).

   Carries the landing page's navbar aesthetic to every page that includes
   components/includes/header.php. The landing page itself (home_new.php) is
   NOT affected: it is a standalone document that ships assets/home/css/styles.css
   and never loads this file.

   SCOPING
   Every class is prefixed `sa-` and every rule is anchored to `.sa-header`.
   That matters because this stylesheet loads alongside Bootstrap 5 and the
   legacy assets/css/style.css, and three of the designer's original class
   names collide outright: `.main-nav` is the legacy Bootstrap navbar, and
   `.button` / `.brand` are generic. Renaming is what keeps the two systems
   from restyling each other.

   The design tokens are redeclared here (scoped to .sa-header) because the
   designer's :root block lives in styles.css, which inner pages do not load.
