   Invoice Maker — design tokens
   Subject: computer sales & repair shop.
   Signature: the "service-ticket" tear-line divider, a faint
   schematic dot-grid backdrop (PCB blueprint), and a rubber-
   stamp treatment for the Paid/Due status — like a real job
   ticket off a workshop counter. Monospace carries every
   number: serials, invoice IDs, money.
