  // folder-transfer (ft) - SERVER config example.
  //
  // Run it with NO subcommand (the first argument is a folder OR this .json):
  //     ft.exe server.example.json          (Windows)
  //     ./ft server.example.json            (Linux)
  //   or just point ft at a folder directly:
  //     ft.exe C:\data
  //
  // On start, ft prints a FINGERPRINT and a ready-to-run command for the RECEIVER, e.g.:
  //     ft get --server <ip> --port 8722 --token <token> --fingerprint <hex>
  // Run that command on the receiver; it then asks where to save (Enter = current folder).
  //
  // Paths: forward slashes "C:/path" OR doubled backslashes "C:\\path".
  // Comments (// and /* */) are allowed. Same keys as the PowerShell ft-server.ps1 config.
