about

nx_mailpiece.nx -- PHYSICAL MAIL COMPOSITION (rung 2 of Nishi Mail to SOTA). Composes a print-ready postcard as an RGB raster and writes it as PNG (preview + the exact bitmap the sovereign print path nx_img_print -> PWG/URF -> IPP feeds to a real printer). NISHI-POSTCARD: 6x4in @300dpi = 1800x1200. FRONT = greeting design (accent bleed + cream panel + centered title). BACK = USPS layout: message on the left, a vertical divider, the recipient address block in the address zone on the right, a stamp (indicia) box top-right, and the lower-right IMb barcode clear zone kept blank by construction. Sovereign: pure integer raster ops + the sovereign 8x8 font; no 3rd party. Last-mile (print vs carrier) is the next rung. Commands: postcard <front.png> <back.png> <greeting> <message> <recipient> <line1> <city> <region> <postal> ; argless = selftest. expect_exit: 0 license_tier: ORIGINAL
