1// nx_census_gallery.nx -- SOVEREIGN visual gallery: the top-20 census as SIDE-BY-SIDE
2// pixels (Chrome oracle | Nishi daily driver) instead of a flat TSV. The TSV stays the
3// census's internal RECORD; this organ is the DELIVERABLE -- humans judge renders by
4// LOOKING, with the measured numbers beside the pixels (the visual-comp law: publish
5// metrics BESIDE the pixels, a number alone can lie).
6//   reads  bench/top20/results.tsv  (site, class, chrome_h, nishi_h, ratio, coarse, tight, recall)
7//   emits  bench/top20/gallery.html (img src = /top20/<name>_*.png, served by the local lane)
8// Uses `break` freely -- safe as of the 2026-07-27 sealed-terminator fix, witness-protected.
9// exit 0 = written; fail-loud otherwise.
