/* ==========================================================================
   blog.css — the /blog index and every article.

   Built on the site's own tokens (--paper, --text-2, --muted, --ink-2,
   --line-soft, --accent-ink …) so light, dark and dim all work without
   overrides. Long-form text keeps a ~70-character measure and generous line
   height: these pages are read, not skimmed past.
