   Centralized blog header + page theme - makes every /blog page
   look identical to the React app (same purple-gradient theme and
   the same glass navbar from client/src/styles/Header.css).
   Namespaced .hra-* so it never collides with per-page blog CSS.
   Loaded after each page's inline <style>, so its body/theme rules
   win at equal specificity. Theme syncs with the app via the
   `darkMode` localStorage key + body.dark-mode / html.dark.
