  Error: Failed to construct 'WebSocket': An insecure WebSocket 
         connection may not be initiated from a page loaded over HTTPS.

  Cause: Production build included webpack-dev-server code that
         tried to open ws:// connection on HTTPS page

└────────────────────────────────────────────────────────────────┘

  1. ✅ Added WDS_SOCKET_PROTOCOL=wss to .env
  2. ✅ Created .env.production (no dev tools)
  3. ✅ Rebuilt: npm run build
  4. ✅ Restarted: systemctl restart church-music-frontend
  5. ✅ Verified: No webpack-dev-server in bundle

  ✓ Bundle size reduced (removed dev server)
  ✓ 0 webpack-dev-server references in build
  ✓ HTTPS site loads without errors
  ✓ No WebSocket security errors

  Production Build:
  $ cd frontend
  $ npm run build
  $ sudo systemctl restart church-music-frontend

  Check Status:
  $ sudo systemctl status church-music-frontend
  $ curl -I https://houseofprayer.ddns.net

  Verify Clean Build:
  $ grep -r "webpack-dev-server" frontend/build/
  (Should return 0 matches)

  ❌ npm start              (Runs webpack-dev-server)
  ❌ react-scripts start    (Development mode)
  
  ✅ npm run build          (Production build)
  ✅ serve -s build         (Static file server)
  ✅ systemctl restart      (Production service)
