- Category Filters: Full category list fetched from OpenTDB; selections are stored locally and can be adjusted at any time.
- Local Question Cache: Each difficulty maintains a stored queue via
expo-sqlite/kv-storefor instant reloads. - Token-based Fetching: Uses the OpenTDB session token to reduce duplicate questions during a session.
