        If this is a tag based topic (no tutorials of it's own)

      Any custom CSS you might want to apply to a specific topic. This could be overriding e.g. the masthead colour (beware, will potentially conflict with themes.)

      This is generally not a recommended property to set on topics, and something that is only used as part of outreach efforts to import content into the GTN.
    examples: |
      - :root { --brand-color: red; }

      The specific learning path you wish to reference as a call-to-action for views who aren't sure where to get started.

      It must be the name of a file in learning-pathways, without the `.md` suffix. This is not validated so, please make sure it's correct :)
    examples:
      - intro-to-galaxy-and-genomics
      - admin-training
