A library color sync wrote a copy's fills through update-shapes, and a
library typography sync wrote a copy text's content with a plain :set,
so both marked the copy as overridden (:fill-group, or :content-group
with :text-content-attribute). A later edit of that fill or text style
in the main then never reached the copy. Both syncs are derived writes:
they now write with ignore-touched.

The typography sync also merged the whole typography into each text node
that uses it, so its :modified-at (and :path) ended in the content of
the main and of every copy. It now writes only the text styles of the
typography.
