An unrelated dependency PR moved Expo to SDK 57 while the app's React Native version, native configuration, and iOS build plan remained on SDK 54. The mobile fix restores Expo 54.0.37 and its expected react-native-svg version. It keeps Metro on a patched 0.83 release so the restored dependency graph does not bring back the vulnerable image-size parser.

Expo Doctor, the iOS JavaScript bundle, lint, typecheck, tests, and a production dependency audit pass locally. No paid EAS build or native TestFlight validation was performed.
