rely/lib/app

App Layer

lib/app/ holds app-level code that is not one product slice:

• relationship_saver_app.dart: root widget and global listeners.
• navigation/: typed shell destinations.
• presentation/: responsive app shell.
• data/: aggregate prototype repository and persistence plumbing.
• state/: shared aggregate snapshot used by the current local-first store.

This is the place to change boot flow, shell behavior, or prototype-wide state composition.
