+<!--
+  Export options for the NucleicRemote iPhone app, used by `xcodebuild -exportArchive`
+  (scripts/ios-release.sh) to produce an App Store build and upload it to App Store Connect
+  (it then appears in TestFlight). `destination = upload` makes exportArchive upload directly
+  rather than writing a local .ipa.
+
+  Note: `method = app-store-connect` is the current name (Xcode 15.3+). On older Xcode use
+  `app-store` instead. Signing is automatic — Xcode manages the distribution profile for team
+  3XPAYVD6BP (needs an "Apple Distribution" cert + the App ID registered; see signing/README.md).
