1// nx_font_legib_census.nx -- what S-CLASS-EXCEED means for LEGIBILITY + ACCESSIBILITY (ADA / dyslexia / low-vision)
2// + BEAUTY, grounded in the Nishi researcher's leg_*.raw (Atkinson Hyperlegible [Braille Institute, low-vision,
3// character disambiguation], Legibility, Readability, Dyslexia, X-height, Frutiger, Verdana). Honest grade of the
4// CURRENT geometric A-Z (nx_font_latin) -- which the operator correctly called blocky/unpolished. ABSENT cells =
5// the redesign targets. GREEN = honest map (not a win). license_tier: ORIGINAL expect_exit: 0
