/* =============================================================================
   ProABD blog (/blog/) — listing pages and articles.

   Restates the landing page's design system for the PHP-rendered blog: the
   tokens come from proabd-landing/src/index.css (@theme), and the nav, buttons,
   hero, cards and footer follow the React components there. Keep the two in
   step when the brand changes.

   Article body markup (.blog-prose and the blog-figure / blog-embed /
   blog-table blocks inside it) is produced by the billing portal's editor; see
   src/lib/blog-content.ts in proabd-billing-portal for exactly what it emits.
