The main text files retain their full upstream glyph coverage, including Latin.
source-sans-3-navigation.woff2 is the unmodified Latin subset served by
Google Fonts
for the reference homepage. Only the Contents
navigation uses this file, registered as Source Sans 3 Navigation with the
same 400, 500, and 600 weight declarations as the reference. This preserves
the reference’s weight selection for its 700-weight Contents heading as well.
The existing source-sans-3-OFL.txt license also applies to this font.
All fonts are served locally, without depending on the Google Fonts CDN at runtime.
