Constant Summary collapse

LABEL_MARGIN =

Page: 288 × 432 pt (4 × 6 in). 5 pt margin each side → 278 × 422 pt usable.

5
LABEL_AVAIL_H =

422 pt

432 - LABEL_MARGIN * 2
EXTRA_PADDING =

Extra bottom padding (pt) added to key cells so the rows fill the 422 pt usable height.
The QR code in the BPS row auto-fills available cell width (~108 pt), so bps padding only
needs to cover the remaining gap after the QR + title, not absorb all the slack.

  5 => { address: 2,  shipping: 2,  po: 2,  bps: 1  },
