1// nx_elara_ref_fetch.nx -- pull the operator's TARGET Elara reference (nishi gallery) over OUR TLS client,
2// save the raw image bytes to knowledge/elara_ref.dat, and print status + size + magic so we know the codec.
3// The critic's grounding: score OUR render against THIS real target, not just abstract axes. expect_exit: 0
