+The `--dynamic` option is required for the host generator in this project.
+This crucial flag instructs the generator to set up the host for dynamic Module Federation.
+This means the host won't have the remote applications' details hardcoded in its `module-federation.config.ts` or `webpack.config.ts` files;
+instead, it will rely on a runtime mechanism to discover them.
