COMPLETE DIAGNOSIS - WHERE CHANGES ARE BEING APPLIED
═══════════════════════════════════════════════════════════════════

YOUR WEBSITE ARCHITECTURE:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. Files Location (SINGLE SOURCE):
   /media/pts/Website/SkyArtShop/website/public/
   
2. Backend (PM2):
   - Serves files from: /media/pts/Website/SkyArtShop/website/
   - Running on: http://localhost:5000
   - Process: skyartshop (PID varies)
   
3. Nginx (Web Server):
   - Proxies page routes (/home, /shop, etc.) → Backend :5000
   - Serves /assets/ directly from: /media/pts/Website/SkyArtShop/website/public/assets/
   - Listening on: http://localhost (port 80)


WHAT I JUST VERIFIED (Live Tests):
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✅ Files on disk have the fix
✅ Backend serves the fixed files
✅ Nginx routes correctly to backend
✅ CSS has correct sticky positioning
✅ HTML structure is correct
✅ Version numbers updated (v=1768449658)
✅ No old folders found


THE CSS IS CORRECT - Here's What's Actually There:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
navbar.css (loads first):
  .sticky-banner-wrapper {
    position: sticky;  ← Makes wrapper stick
    top: 0;
    z-index: 1000;
  }
  .modern-navbar {
    position: relative;  ← Navbar inside sticky wrapper
  }

page-overrides.css (loads after):
  .modern-navbar {
    /* position: relative !important; - REMOVED */  ← Fixed!
    overflow: visible !important;
  }


THE PROBLEM IS BROWSER CACHE:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Even with version numbers (v=1768449658), your browser may have:
1. Cached the OLD CSS files in memory
2. Service Worker cache (if any)
3. Disk cache ignoring query strings
4. CDN cache (if behind Cloudflare/CDN)


HOW TO FORCE A COMPLETE REFRESH:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Method 1 - Hard Refresh (Try First):
  Windows/Linux: Ctrl + Shift + R
  Mac: Cmd + Shift + R
  
Method 2 - Clear Cache Manually:
  Chrome: F12 → Network tab → Check "Disable cache" → Refresh
  Firefox: F12 → Network tab → Click gear → Check "Disable Cache"
  
Method 3 - Incognito/Private Window:
  Open http://localhost/home in private/incognito mode
  
Method 4 - Clear Browser Cache Completely:
  Chrome: Settings → Privacy → Clear browsing data → Cached files
  Firefox: Settings → Privacy → Clear Data → Cached Web Content


TEST PAGE CREATED:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
I created a simple test page with MINIMAL code:
  http://localhost:5000/test-sticky-navbar.html
  
Open this in your browser:
  - If navbar STICKS → CSS is working, main pages have browser cache
  - If navbar SCROLLS → Need to check browser console for errors


CHANGES ARE APPLIED TO:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✅ /media/pts/Website/SkyArtShop/website/public/home.html
✅ /media/pts/Website/SkyArtShop/website/public/assets/css/navbar.css
✅ /media/pts/Website/SkyArtShop/website/public/assets/css/page-overrides.css
✅ All 14 HTML pages (home, shop, portfolio, about, contact, blog, etc.)

These are the ONLY files. There are NO old versions anywhere.


NEXT STEPS:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. Open browser DevTools (F12)
2. Go to Network tab
3. Check "Disable cache"
4. Refresh page (F5)
5. Check if navbar.css and page-overrides.css load
6. Look at Console tab for any errors
7. Try the test page: http://localhost:5000/test-sticky-navbar.html

If test page works but home doesn't → Check browser console for errors
If test page also fails → Check if there's an HTTPS/security issue
