/* Shared editorial shell for hand-authored blog posts.
   Matches the design language of Blog Exploratory Testing and the four
   per-post designs (signs-outgrown, setup, manual+automation, pricing).
   Ported to site.css tokens so light + dark via prefers-color-scheme just
   works. Scoped to .blog-post — does NOT leak to other sections. */
