   Palette from the subject: cyanotype blueprints were how charts and
   engineering drawings were copied. Prussian blue blocks, paper off-white,
   a redline accent for review marks only. Grain on the blue.
   Layout: 12 columns on a 1320px measure; full-bleed colour blocks.
   Type: Switzer (300/400/500) + Geist Mono, from the kaviyan build.
