   Watchdog HQ — site chrome (nav + cta-foot + footer)

   Extracted 2026-05-06 from landing/about.html to give the programmatic
   blog (ADO-31280) and regulations (ADO-31281) generators the same
   header/footer styling as the hand-built pages without copy-pasting
   ~150 lines into each generator.

   This file ONLY covers chrome — page-specific layout (.about-hero,
   .legal-hero, .post-hero, .topic-hero) stays inline on each page so
   the visual identity of each surface is still owned by that surface.

   To add a new page that should match the site chrome:
       <link rel="stylesheet" href="assets/brand.css">
       <link rel="stylesheet" href="assets/site-chrome.css">

   Existing hand-built pages (index.html, about.html, terms.html,
   privacy.html) still inline their chrome — they were built before
   this file existed. Migrating them is a separate, lower-priority
   refactor; the inline CSS is byte-identical to what's here, so a
   later DRY pass can drop the duplicated <style> blocks safely.
