Description: The SellSEO blog, built on the same design system as the app. It loads the site's own /assets/app.css rather than restating the tokens, so the blog cannot drift away from sellseo.ai; everything below is only what a blog needs and the app does not have.

   Everything here assumes /assets/app.css is already loaded: the
   colours, buttons, pills, .section, .card, .footer and the nav are
   all its. Only blog-shaped things live in this file.

/* ---------- Utilities the app's stylesheet does not carry ----------
   app.css was written for the app, which never needed a visually-hidden
   class; WordPress core markup (labels, pagination, comment forms) emits
   .screen-reader-text and expects it to exist. Without these the search
   form's label sits in the sidebar as loose visible text. */
