* Allow OFL typefaces whoever designed them (AGENTS.md §1.1) Noto CJK and Source Han from their open-source releases are allowed like any other OFL font. The fonts build no longer skips them, the asset check accepts an OFL font credited to Adobe, and the docs describe the Chinese faces that result. The ban on Adobe icons, artwork, UI graphics and the fonts Adobe products install stays. * Leave out whole CJK faces other than the Japanese ones for size A Chinese or Korean face is embedded whole only under 4 MiB, so the 16.4 MB Noto Sans CJK SC in craft-fonts stays out of the binary and the embedded total against the pinned craft-fonts is unchanged (25,204,828 bytes). * docs: replacement boxes for Chinese without craft-fonts only on the web or without an installed Chinese face * xtask assets: the OFL font exemption needs at least one licence ID * fonts build: count a CJK script tag with a region (Hant-HK) as CJK, shared with the embedding test * AGENTS.md: the asset gate exempts OFL fonts from the Adobe-author check * fonts build: count a Hangul-only face (Hang) as CJK for the size rule * fonts: the CJK embedding test checks the size rule, sharing its constants with build.rs * docs: the missing Hans face is a property of the pinned craft-fonts, not of every build
