+POS: Block barcode scanning on error popup
+=========================================
+
+Summary
+-------
+This Point of Sale extension prevents the POS from processing further barcode
+scans while the "barcode not found" error popup is visible. It also avoids the
+scanner's Enter/Escape keystrokes from closing the popup, so the cashier must
+explicitly dismiss it (click/tap) before continuing.
+
+Features
+--------
+- Takes exclusive control of the barcode reader while the error popup is shown.
+- Prevents scanner-triggered keyboard "clicks" from closing the popup.
+- Keeps the initial error message visible; subsequent scans are ignored.
+- Includes CSS to highlight the error popup for better visibility.
+
+Usage
+-----
+- Scan a non-existent barcode in the POS.
+  - The error popup will show.
+  - Further scans will be ignored while the popup is visible.
+  - Close the popup via mouse/touch to resume scanning.
+
+Limitations
+-----------
+- While the popup is open, all barcode actions are blocked (product, client,
+  weight, price, discount, GS1, etc.). Customize the hook if you need
+  exceptions.
