 * A data persistence layer for storing application settings, modelled after

 *
 * Values are saved in a `config.json` file in `app.getPath('userData')`.
 *
 * Compatibility:
 * - Maintains API and file format compatibility with `electron-store@8.2.0`.
 * - Supports the Electron main process only.
