/* ============================================================================
   Red Thread Labs — Blog chrome  (blog/blog.css)

   Shared navigation + call-to-action styling for every page under /blog/.
   Depends on the brand tokens in ../rtl-theme.css. Link both, in this order:

     <link rel="stylesheet" href="../rtl-theme.css">
     <link rel="stylesheet" href="blog.css">

   The CTA markup itself is injected by blog-cta.js — see that file.
