flags.woff2, and where it came from

The font beside this file draws the country flags the browser view shows. It
is shipped rather than fetched, and it is the only thing in this package that
is somebody else's work rather than this project's, so this is here to say
whose and under what terms. It travels in the wheel with the font, because the
licence on the artwork asks for the credit to go wherever the material does.

  changes   none. The file is byte for byte the one in that package.

The font is COLR and CPAL, which is to say layered vector colour, and it holds
the flag sequences and nothing else: 78 KB rather than the several megabytes a
whole emoji font costs.

Nothing else from that package is here. The JavaScript half of it decides at
runtime whether a browser needs the font; this program does not ask, and
decides something else instead. A page that is marking countries fetches it
and a page that is not never does, and the unicode-range on the face keeps it
to the flag letters once it is here, so a machine that already draws flags
goes on using its own font for every other character on the page.
