Problem

You're putting an HR export into a stable reporting order: a list of `records`, each a dict carrying the same fields, plus an ordered list of field names `keys`. Return a new list sorted ascending by the first key, breaking ties with the next key, and so on down the list.

Summary

When two things tie, something has to break the deadlock.
