the face is Zen, and it ships from @hanzo/font

One family. Font stacks name Zen and fall back to the native faces, tokens
name the role rather than a face, and the packages that used to supply a
face now point at @hanzo/font.

Self-hosted @font-face blocks are removed rather than renamed: rewriting the
family in one would leave a src pointing at a file this repo no longer ships.
@hanzo/font carries the binaries and declares the faces, so the local copies
go with the declaration that used them.

Comments naming a face we no longer use are deleted, not reworded.
