The previous commit edited these three files through a JSON round-trip that
reindented them to one space, which made dns-config the only case formatted
differently and buried a three-line change in 220 lines of whitespace.
The comparison unmarshals before diffing, so the layout was never load-bearing;
this is purely about the diff a reviewer has to read. Same content, edited in
place this time.
