-## What it does
+Luggage List is a local-first Expo app for keeping trips, luggage, and check-ups organized without a server, login, or cloud sync.
 
-- No auth, no server, local storage only (AsyncStorage)
+## Highlights
-- Trips with name, location, start/end dates, optional image, and archive support
-- Active trip auto-select on first load, with a global trip picker for manual switching
-- Default trip template, copied into new trips
-- Luggage items with:
-  - name, quantity, description, category
-  - status: packed, unpacked, lost, left-behind, lent-to
-  - placement: suitcase, backpack, with-user, other
-  - optional images, gallery pick, camera capture, crop, and quality settings
-- Item create/edit via modal, with bulk and quick status updates
-- Check-up flow as a yes/no checklist with live stats
-  - “No” opens an update modal
-  - fixes can stay check-up-only or sync back to the trip item list
-- Check-up history per trip with saved snapshots and stats
-- Backup and restore via JSON file or pasted JSON
