/* Most handheld/desktop thermal barcode printers (e.g. "4BARCODE 2B-220B")
   use a fixed 50mm-wide label roll with their own driver-defined label
   height — they ignore custom @page sizes that don't match a size they
   already know. Keeping the label small (well under a typical 25-30mm
   label height) means it fits on one physical label regardless of which
   preset the printer driver ends up using.
   Named page "label-page" (set via the `page:` property on .barcode-label
   above) keeps this sizing isolated from the receipt's 80mm @page rule,
   so the two print jobs never fight over the paper size. */
