   pamphlet.css: shared print-ready pamphlet styles

   Used by the single-sheet Letter pamphlets: setup.html (Quick Start) and
   features.html (Features). Each page links this file, then adds only its own
   page-specific bits inline (setup: QR codes; features: none). Screen shows a
   simulated Letter sheet; @media print flattens it to real paper.
