/* Digital 1010 · «postales y cartas de costa».
   Cool chart paper, near-black ink, one colour per type of place. Pairs are postcards: a photo or,
   without one, the place set in type on the section colour; a round postmark carries the section
   and the date of the check, and the distance goes on a perforated postage stamp.
   build.py sets --sec on a section's blocks from site.json color_token. */
