/* =====================================================
   All Tools page (homepage-matching design, live since 2026-10-04)
   Used only by app/Views/pages/all-tools.php.

   Loaded AFTER home.css: reuses the homepage's tokens and building
   blocks (.hv1 colours, .hv1-hero, .hv1-tool cards, .hv1-cta ...), so
   changing those in home.css changes this page too, on purpose. This
   file only adds the .at-* parts: centred hero with a filter box, the
   category chip panel over the hero edge, and the per-category groups.
