   TamingDNS Articles — Direction B (tools-grid match).
   Self-contained: loaded only on /articles and /articles/{slug} via the
   $pageExtraCss hook in head.php. Every colour resolves to an existing theme
   token (or one of the six article tokens defined here for both themes), so
   the dark-mode toggle flips it in lockstep with the rest of the site.
   Lifted from blog-mockups.html; literals swapped for tokens.
