   YUME — the log
   A reading room next door to the instrument panel. Same person, same
   palette, quieter room: no scripts at all, no tracking, no cookies.
   Latin text is set in a newspaper serif; Japanese falls through to the
   mincho already on the reader's machine, so a post in either language
   is set properly without shipping a five-megabyte font to do it.
