about
nx_font_ttf_emit.nx -- R2 of the sovereign-font ladder (the KEYSTONE): serialize the R1 glyph outline model
into a REAL TrueType .ttf (sfnt: OS/2 cmap glyf head hhea hmtx loca maxp name post, big-endian, per-table
checksums + head.checkSumAdjustment) -> web_assets/nishi.ttf. Then SELF-VALIDATE by re-parsing the emitted
bytes (sfntVersion, numTables, every dir offset/length in bounds, every table checksum recomputed [head
special], and the whole-file checksum == 0xB1B0AFBA) -> sovereign verification, not assumed. Glyphs:
.notdef space H I T, in-house designs, 1000-EM. license_tier: ORIGINAL expect_exit: 0
