/* ===================================================================
   All-tools directory. Loaded only by tools.cshtml, after the shared
   template stylesheet, and scoped under .toolspage throughout.

   Design tokens come from a2z-tokens.css, shared with the home page -
   this is the same product, so it is the same palette, radii and
   shadows. Mobile-first: base rules are the phone layout and the media
   queries only add.

   The page no longer uses .search-block / .search-below-wrpr /
   .icon-list-hero from the template stylesheet. Those are still used by
   index-design.cshtml and category-details.cshtml and are deliberately
   left alone.
