expo-router@6.0.23 declares react-dom as peerOptional; without an explicit
pin npm resolves react-dom@19.2.5 (latest) which conflicts with react@19.1.0.
The SDK 54 template pins both to 19.1.0 — mirroring that here.
react-dom@19.2.5 (pulled by @expo/router-server) requires react@^19.2.5;
@react-native/virtualized-lists@0.85.2 requires @types/react@^19.2.0.
npm install now completes without errors or warnings.
