The rendering doc's running log of finished work is folded into the
architecture section and the rest dropped: what remains is why the code
is the way it is, the harness, and what is next.
The highlights bug is bigger than the backwards span we already drop.
The library pairs every `/*` with an `*/` by ordinal position and uses
the same delimiters for every language, so a shell glob opens a comment
and `//` in any URL comments out the rest of its line, taking the
keywords and strings inside it with it. highlights-repro.sh asks the
library directly, outside the app, since none of this is visible on a
phone.
