- * Application-level singleton cache for Nostr user profiles.

- * concern used by every screen that displays user metadata.
- *
- * Long-running tasks ([runObserver], [runMetadataBatching]) run in a dedicated
- * [CoroutineScope] that outlives any individual screen, ensuring continuous operation
- * regardless of navigation.
