about

nx_typequality_census.nx -- MEASURE typeface QUALITY vs Chrome's professional font (operator: legibility is proven but the type "is pretty good but still bad" -- so quantify the REAL quality gap, not just legibility/smoothness). Renders the SAME word ("Render legibility") in our vector font and in Chrome (Arial 600) at matched size; decodes both; measures the visible amateur-vs-pro tells: WEIGHT = ink density within the tight text bounding box (professional display type is BOLD/confident; ours was thin -> low). ratio = ours*1000/chrome. STROKE = average dark run-width (px) -- thin hairline strokes vs solid ones. This census is HONEST BY DESIGN: it REPORTS the gap (does not claim parity). C-tests assert the comparison exists + the metric discriminates (Chrome must read as heavier than a blank). The verdict is census integrity; the numbers speak. license_tier: ORIGINAL expect_exit: 0
