/* ============================================================
   includes-header-footer.css  (FIXED)
   ============================================================
   Drop-in replacement for the Header / Footer sections of
   style.css. Same class names, same color/spacing tokens --
   only the layout rules changed. Paste this OVER the existing
   ".site-header" through ".footer-bottom" block in style.css.

   WHAT WAS WRONG BEFORE:
   1. No flex-wrap / min-width:0 on .header-container, so on
      narrow screens the logo + search bar + nav buttons were
      forced into one unbreakable row -> horizontal scrollbar
      (the "X axis" issue).
   2. .header-search had no min-width:0, so a flex child with
      text content refused to shrink below its content size,
      pushing everything else off-screen.
   3. No @media rules at all for header or footer -- nothing
      adapted for mobile.
   4. .header-nav had no wrapping/mobile-collapse behavior.

   THE FIX:
   - min-width:0 on every flex child that can hold long content
   - a real mobile hamburger toggle (.header-mobile-toggle) that
     shows under 720px and collapses .header-nav into a dropdown
   - the search bar hides under 560px (still reachable via the
     dedicated /pages/search.php page) to keep the bar usable
   - footer grid collapses to 1 column on small screens
