/* PayLink — "Precision Terminal".
   A payment terminal drawn with Swiss typographic discipline.
   Signal colour: laterite orange, the red earth of Madagascar (the Red Island).
   One cultural mark: a woven lamba band on the printed counter card.
   Type: Archivo (variable width + weight) for words and instrument numerals,
   Martian Mono for engraved labels, ids and addresses. Both SIL OFL, self-hosted. */
