/* ============================================================
   HEADER  +  TOPBAR  +  FOOTER
   Single source of truth. No duplicate rules.

   LAYOUT STRATEGY
   ------------------------------------------------------------
   - .navbar          : max-width 1400px, centered. Owns
                         Company Logo + Navigation.
   - .navbar-credentials : absolutely anchored inside <header>
                         the topbar bar, far-left edge, vertically
                         centered. Always visible on desktop so
                         they are pinned to the topbar on every
                         reasonable viewport. Mobile hides them.
                        Per project priority:
                          1. Company Logo
                          2. Navigation
                          3. Certification Logos
