/* ==========================================================================
   Site map  (/sitemap/)

   A utility page: every page on the site, generated by tools/gen-sitemap.mjs.
   Shared, from stylesheets already linked: the page banner.
   Page-local (the search field and jump bar follow the Glossary's):
     .smap-search   the banner's page filter
     .smap-index    the section jump bar, sticky at the top
     .smap-section  one top-level section: H2, page count, its groups
     .smap-band     a page whose children have children (AI-Driven Design,
                    Design IP): its children laid out as columns, full width
     .smap-col      a page with children: its title and their list
     .smap-col--plain  consecutive pages without children, one plain list

     §1 banner white · §2 jump bar white, sticky · §3 tree white
