    Hint: To resolve the conflicts, start by creating a commit on top of
    one of the first conflicted commits:
      jj new lylxulpl
      jj new kmkuslsw
    Then use `jj resolve`, or edit the conflict markers in the file directly.
    Once the conflicts are resolved, you can inspect the result with `jj diff`.
    Then run `jj squash` to move the resolution into the conflicted commit.
