Offline-First
Short definition
A design pattern where the app works fully without internet, then syncs data automatically when connectivity returns.
Extended definition
Offline-first design means the app stores all data locally (in SQLite or Hive) and operates on it immediately. Every change is added to a "sync queue", and when internet returns, everything uploads automatically. This pattern is essential in markets with intermittent connectivity.
