/* ============================================================
   Honestly concept — shared site chrome (announcement, nav, footer)
   Self-contained styles so every concept page renders the SAME
   top navigation and footer as index.html.

   Load this BEFORE a page's own stylesheet so the page's own CSS
   still wins any conflict on shared utility classes.

   Rules below are copied verbatim from styles.css. The only
   additions are two clearly-marked "chrome consistency guards" at
   the very bottom, scoped to .site-nav so page bodies are never
   affected (see the comment there).

   Some concept pages load their own stylesheet AFTER this file and
   redefine :root tokens (e.g. --ink) or the base .button (e.g. a

   and make the header look slightly different per page. These two
