  Pasture Ledger - stylesheet
  Aesthetic direction: "Feed Store Ledger" (see DESIGN.md for the full rationale
  and the two directions not taken). Warm parchment surfaces, barn-red and
  pasture-green accents, a vendored slab serif for a stamped-ledger feel, tuned
  for outdoor daylight legibility and one-handed use.
