+# Standalone, manually-dispatched build that compiles the changed native file
+# (RCTDeviceInfo.mm) via the traditional CocoaPods RNTester integration —
+# self-contained, unlike the repo's normal iOS CI (test-ios-spm-rntester.yml /
+# e2e-ios-rntester.yml), which depend on prebuilt xcframework artifacts from
+# earlier jobs in test-all.yml and can't be dispatched on their own.
