/* ============================================================
   RefAssign — shared header/nav/footer "chrome".
   Matches the Gamedata Solutions corporate design system used by
   scoresheets.ca / matrixBuilder / draftScheduler: dark header with
   logo + a permanent hamburger dropdown menu (all viewport widths,
   not a mobile-only collapse), a version badge, and a copyright/
   version footer.
   Loaded before each page's own <style> block, so a page can still
   override a single property (e.g. .header-container's max-width,
   which intentionally differs per page to match that page's content
   width) via the normal cascade.
