The `+N` span sat outside `.summary` to survive its ellipsis, which also
left it outside that rule's font-size and line-height. The web shell
leaves body text at the browser default, so the count rendered larger
than the 14px/24px text beside it on the same 24px row.
Also restores the fs-edit fixture's recorded `/private/tmp` cwd spelling,
which a re-record on Linux had rewritten to `/tmp`. The normalizer already
collapses the `/private` prefix onto the cwd token, so the recorded
spelling replays on both platforms and the fixture matches master.
