-/**
- * Alternatively, import toolkit modules you use to minify the plugin size.
- *
- * Steps to replace the default `ztoolkit: ZoteroToolkit` with your `ztoolkit: MyToolkit`:
- *
- * 1. Uncomment this file's line 30:            `ztoolkit: new MyToolkit(),`
- *    and comment line 31:                      `ztoolkit: new ZoteroToolkit(),`.
- * 2. Uncomment this file's line 10:            `ztoolkit: MyToolkit;` in this file
- *    and comment line 11:                      `ztoolkit: ZoteroToolkit;`.
- * 3. Uncomment `./typing/global.d.ts` line 12: `declare const ztoolkit: import("../src/addon").MyToolkit;`
- *    and comment line 13:                      `declare const ztoolkit: import("zotero-plugin-toolkit").ZoteroToolkit;`.
- *
- * You can now add the modules under the `MyToolkit` class.
