+When running on an Apple Silicon Mac and building only for the simulator used in the current run, prefer compiling only the active `arm64` simulator architecture:

+
+Use this optimization only for local self-test / e2e simulator builds tied to the current machine. Do not use it when you need a universal simulator app for other machines or when running on Intel Macs.

+## Prod iOS auth bootstrap
+
+When non-auth iOS self-tests need a signed-in simulator quickly, bootstrap auth through the standard iOS runner mode:
+
+```bash
+pnpm run e2e:ios:bootstrap
+```
+
+This mode uses the auth bootstrap helper on iOS when `EXPO_PUBLIC_E2E_ENV_PROFILE=prod` or `EXPO_PUBLIC_E2E_ENV_PROFILE=local`, and falls back to the normal iOS registration flow for other environments.
+
+Optional environment variables:
+
+- `E2E_EMAIL`
+- `E2E_PASSWORD`
+- `MAESTRO_IOS_DEVICE_ID`
+- `E2E_API_URL`
+- `E2E_CALLBACK_URL`
+- `E2E_BUNDLE_ID`
+
+The bootstrap script signs in against prod using the mobile fallback token header, writes the auth cookie into the simulator's `ExpoSQLiteStorage` fallback store, and relaunches the app.
