   Bradley Hartwick — Product Portfolio
   Light-first editorial print surface.
   Letter landscape, 11 x 8.5 in, 0.5 in outer margins, 12-column live area.
   Minimalist, light, editorial: generous air, confident type, one restrained
   accent, delicate rules. No cards, glass, blur, gradients, rounded
   containers, or reticle motifs. Reconstructed / redacted / pending work is
   always labelled.
