   NODDIE NIGHT — blog.css
   The Noddie Night Journal: minimalist sleep-education blog. Loaded on
   /blog/ (index) and /blog/<slug>.html (post) pages only, AFTER site.css
   and pages.css (tokens, base type, buttons, header/footer, .prose,
   .callout, .table, page-hero/page-wrap/breadcrumb/page-title/page-lede/
   article-meta/page-body/page-layout/.toc/.page-prose/.article-figure/
   .fine-print all live there and are reused verbatim by the blog).

   Order: shared post-card component · index (intro, category chips,
   featured, category grid sections) · post (measure, blockquote, inline
   images, "In this article" tweak, FAQ, quiet CTA, keep reading,
   disclaimer) · print · reduced motion.

   Mobile-first. Nothing here may cause horizontal scroll at 360px.
