/* Shipping-label typography on stamp-ink colours.
   The parcel number is the artifact this app is about, so it is set large and
   monospaced; everything that labels rather than states is small, letterspaced
   and uppercase, the way a waybill sets its field names.

   System faces on purpose: on the iPhone this resolves to SF Pro and SF Mono,
   which are excellent, need no network round-trip, and keep a Home Screen app
   feeling native. A webfont here would only add a blocking request. */
