/*
  Dokpa Garment, Kathmandu Workroom study.
  Documentary newsprint. Warm cream stock, ink black, one vermilion accent.
  Shared by index.html, contact-sheet.html, garment-notes.html, visit.html.

  Deliberately unlike the Himalayan Craft study in this repo: greyer pulp
  cream instead of golden paper, slab plus grotesque instead of Fraunces over
  Karla, a fixed contact sheet grid instead of magazine compositions, and a
  caption led hierarchy rather than a headline led one.
