   Tokens for the how-to documentation kit only. These are plain
   custom-property declarations: they apply NO styling on their
   own and are consumed exclusively by the .tpldoc-* classes

   affected. Re-theme the kit by editing values here.
   When you add new .tpldoc-* styles, reuse these tokens.
