Latin (IBM Plex) is the web default, International (adds the CJK and emoji faces) the
desktop default; app_main! records the choice before widgets register, the theme only
registers the selected chains, a glyph miss never starts a load, and the resolved font
resources are emitted as the makepad.font-assets.v1 section for the packager.
