   VERSION: 4.0.0
   PURPOSE: Clean, full-width dashboard layout for the AviaSAFE SMS UI.
            - Fixed full-width header with brand, nav (WordPress-style dropdowns)
              and user/logout — NO sidebar, NO hamburger, NO overlay
            - Two-row header: Top (brand + user) / Yellow divider / Bottom (nav)
            - Page hero (airline name + department subtitle)
            - Main content full width
            - Single-line footer
            - Breakpoints: 768px
