    # NOTE: Instead of having a separate secrets directory, you could hardcode
    # the secrets into app.ini. This extra indirection just lets us share our
    # app.ini publicly, while keeping the secret tokens in gitignored files.
    # Also, the directory name "secrets" and the file names we chose aren't
    # reserved by Forgejo! Forgejo simply ignores any unrecognized files in
    # /etc/forgejo, then we reference our secret files by path in app.ini.
