/* Lloyal docs.

   One stylesheet, written against tokens. Dark is the default and matches
   lloyal.ai (public/styles.css there); light is the blog's article palette
   (public/blog/assets/lloyal-docs.css). A colour belongs in a token, never in
   a rule — that is what lets one set of rules serve both themes. */
