nx_png_lum.nx -- sovereign PNG mean-luminance probe over a content rectangle. Turns "the page looks dark" into a NUMBER (mean luma 0..255) measured from the actual rendered pixels -- the "show proof not I can see" tool for the S21 browser dogfood before/after. usage: nx_png_lum <file.png>. Samples y[100..h-40] x[60..w-40] (skips the white browser chrome bar at top). license_tier: ORIGINAL
