/* ============================================================
   FinsiderAI — Global layout (header + footer + shared utilities)
   Loaded on every page via base.php, AFTER components.css and
   BEFORE any page-specific stylesheet.

   Contents:
     1. .container utility (shared by header, footer, every page)
     2. Site header (sticky bar, brand, search)
     3. Mega menu (desktop dropdown + mobile drawer + accordion)
     4. Header/menu breakpoint switches
     5. Site footer (newsletter band, trust strip, link grid,
        social row, bottom strip)
     6. Disclaimer band (below footer)
     7. Mobile overrides for header/footer (≤ 600px, ≤ 380px)

   Source of truth for design values: tokens.css.
