+ * We are using a .cjs extension because:
+ *
+ * 1. Webpack CLI only supports CommonJS modules;
+ * 2. tgui-dev-server supports both, but we still need to signal NodeJS
+ * to import it as a CommonJS module, hence .cjs extension.
+ *
+ * We need to copy-paste the whole "multiline" function because we can't
+ * synchronously import an ES module from a CommonJS module.
+ *
+ * This plugin saves overall about 10KB on the final bundle size, so it's
+ * sort of worth it.
