/* ==================================================================
   WATERWISE SHARED CHROME — header + footer styles
   Single source of truth for every page's header/nav/footer visuals.
   Extracted from shop.html (most complete existing implementation).
   Loaded by every page; markup itself is injected by js/ww-header.js
   and js/ww-footer.js so there is exactly one copy of the DOM too.
