/* ============================================================
   css/blog.css — the blog in the Nebula interface (owner, 2026-10-10).

   Loaded after css/ui-v2.css by blog/index.html and every article; every
   rule hangs off html.ui-v2 like the rest of the interface, so it sits over
   each page's own inline styles without touching their markup. js/blog.js
   adds the interactive parts (search and topic filter on the index; the
   reading progress bar, the contents rail and the reveal on articles).
