   ForeverAfter.life — Blog (index, category pages, article)
   Local tokens alias the site's --ff-* scale, the same way quotes.css does, so
   these pages inherit the shared palette rather than carrying their own.
   Loaded only on the blog pages (linked from their templates).

/* Scoped to the blog's own roots rather than :root. Two of the names below --
   --font-sans and --accent -- are the design system's as well, and the admin
   article preview loads this file on a page that already owns them: written
   onto :root there they resolved to nothing (the --ff-* originals only exist
   on the public layout), which invalidated `body { font-family: var(--font-sans) }`
   and dropped the whole admin chrome to Times. Every rule in this file is
   inside the .ba-* namespace, so the tokens only ever need to reach these
   roots and what they contain. */
