/* /what-we-build/segments: the second capability page. Layers on top of
   base.css.

   Section order matches src/views/what-we-build-segments.ejs and the
   capability-page structure in SITE-ARCHITECTURE.md section 5.

   Deliberately close to build.ranking.css. The two capability pages
   should read as the same page type, so the hero, the settles grid, the
   dark two-column split, the onward cards and the closing block are the
   same shapes at the same sizes. Where a rule here is identical to one
   there, that is on purpose and not a copy-paste to be factored out:
   they are separate pages and either can move without dragging the other.

   The genuinely new component is the group card, which carries a figure
   panel and a published rule. It is a card rather than a table row
   because a group's rule runs to forty words and a table would set it at
   a size nobody reads. */
