+// Reusable capture box for USB/Bluetooth barcode & RFID scanners. Those devices are plain HID
+// keyboards: they "type" the scanned code into whatever input is focused, then send Enter — so
+// there is no camera/getUserMedia code here, just a text input that reacts to Enter (and to
+// losing focus with content still in it, in case a scanner is configured without a trailing
+// Enter) and clears itself after each read. It stays auto-focused so the next scan always lands
+// here rather than wherever the cursor last was in a large form.
