about

nx_aatext_proof.nx -- prove GRAYSCALE-AA text from the full-ASCII 8x8 font via coverage supersampling, vs the current 1-bit blocky render. Same string, 3 rows: 8px 1:1, 16px blocky, 16px coverage-AA. If the AA row reads clearly smoother, this is the drop-in quality jump for the browser (full ASCII, no new font).
