   Ported from the ITCS "Series Journey" design. Scoped under .blog-scope

   the SSI header/footer. Headings use Nunito (site brand); body Open Sans.
   Dark mode is driven entirely by re-defining the tokens below, so almost
   every component adapts automatically via var(--card)/--ink/--line/etc.
