Add a class

Your own classes sit alongside the built-in ones and travel with labels.json, so committing that file carries them to the live site.

Save classifications back to the site

The page can commit labels.json to your repository each time you classify, so the published site stays current without you exporting anything.

This needs a GitHub token, which is stored only in this browser. Use a fine-grained token limited to this one repository with Contents: read and write, and only on a machine that is yours. Anyone with access to this browser profile could read it and write to that repo until it expires.
