/* contextkit.outhad.com: one stylesheet for the landing page, the docs, and the changelog.
   Design: one variable family (Recursive) in three voices. Casual is what people say, linear is
   prose, mono is what ContextKit keeps. A peach highlighter (the Outhad accent) marks what is
   remembered; everything else is quiet ink on cool paper. Follows the system light or dark setting. */
