Nail Salon Solution

Version 7.01 — Offline Mode for Manager Role - Works without internet: Manager dashboard and appointments fully functional when offline — tech turn actions (move to working, complete, remove, continue, add to standby) apply immediately to the UI and queue for sync later - Local appointment storage: All appointments cached on-device; new appointments can be created offline with offline_ prefix IDs, visible in both appointment views and time slot selection - Undo works offline: All undo actions detect offline state, queue reverse actions, and update the UI locally - Auto-sync on reconnect: Queued actions replay automatically when connection returns (2s debounce on any successful API call, plus 15s health check as backup) - Conflict resolution: Timestamp-based — queued tech actions compared against server updatedAt, only newer actions applied; server wins if more recent - Duplicate prevention: Queue cleared atomically before execution; offline appointment placeholders deduplicated against server data by composite key (tech+date+timeslot+phone) - Minimal status dot: Replaced verbose banners with a 12px dot on ManagerHomeScreen — red = offline, yellow = backup server, blue = syncing - Polling guards: All periodic fetches and focus refreshes skip when offline to prevent overwriting local state - iOS deployment target: Raised to 14.0 (from 13.4) for NetInfo compatibility - Build: 15 → 16
