   MIRRORED FROM web/app/globals.css. That file is the source of truth.

   This is the drift tax we accepted when choosing WordPress over a custom
   blog: the header and footer now exist twice, in two languages. If you
   change the nav, the logo, the palette or the button styles there, change
   them here too, or a reader clicking from an article to /pricing will
   watch the site change shape under them.

   Mirrored below: the :root tokens, .cf-header, .cf-nav, .cf-btn,
   .cf-footer. Everything after the BLOG-ONLY marker is ours alone and has
   no counterpart to keep in step.
