/* ── Helloforward blog: the marketing site's theme, verbatim ──────────────
   The blog is static HTML under /blog/, outside the React bundle, so it can't
   import src/index.css. Everything here is copied from that file's customer
   surface (`:root[data-surface='user']`): the same floor-and-card tokens, the
   same nav, buttons and footer, the same serif/sans pairing. No gradients, no
   grain, no atmosphere of its own: the blog is a page of the site, not a site.
   If index.css changes a token, change it here too. */
