1. Add to any HTML page:
   <link rel="stylesheet" href="css/offline-queue.css">
   <script src="js/offline-queue.js"></script>

2. Replace fetch() with queuedFetch():
   const response = await queuedFetch(url, options, 'requestType');

3. Handle queued responses:
   const result = await response.json();
   if (result.queued) {
       alert('Queued for sync when online');
   }

1. Open: http://your-server/CLCI/App/test-offline-queue.html
2. DevTools (F12) → Network → Set to "Offline"
3. Click "Send Test Request"
4. See orange banner: "Offline (1 pending)"
5. Set back to "Online"
6. Watch auto-sync in console
7. See green notification: "Synced test-normal"

SCENARIO: Field worker at remote job site

08:00 Office (Online)     → Clock-in: Sent ✅
08:30 Driving (Online)    → Breadcrumbs: Sent ✅
09:00 Remote (Offline)    → Breadcrumbs: Queued 📲
10:00 Remote (Offline)    → More breadcrumbs: Queued 📲
17:00 Remote (Offline)    → Clock-out: Queued ⏰
17:30 Driving (Online)    → Everything auto-syncs 🔄
18:00 Office              → All data saved! ✅

RESULT: Zero data loss, automatic sync, no user intervention!
