/* Boridesk blog — shared page chrome, generated cover art, and article
   typography. Mirrors the token set and nav/footer styling used by the
   legal pages so the blog reads as part of the same site.
   Cover art is CSS-generated (no image assets) so new posts need no
   design work — pick a data-cover value and it themes itself. */
