1// nx_print_send.nx -- PHYSICAL Print-Job: submit the sovereign .urf artifact to the real Brother and
2// print a page. This is OUTWARD-FACING + consumes paper/toner -> run ONLY on explicit operator consent.
3// Reads knowledge/fetched/nishi_test.urf, builds a Print-Job (image/urf), POSTs it, reports job-id/state.
4// Still never-brick (#26): it submits a normal print job; it writes no firmware/NVRAM. license_tier: ORIGINAL
