1// nx_font_pioneer_benchmark.nx -- the PIONEER FONT BENCHMARK. Composes the per-axis font-quality censuses
2// (each liar-killed + Chrome-grounded) into ONE honest scorecard: is our sovereign stroke font at Chrome's
3// professional standard, axis by axis, MEASURED? Reads the log lines the sub-censuses emit (weight ratio,
4// faceting toward-hexagon, baseline bounce vs Chrome, OCR legibility) -> a scorecard + HTML. This is the
5// "pioneer for benchmarking": run the 4 sub-censuses, then this. Honest about the axes still short of SOTA.
