> Currently, `update_copyright_year.sh` hardcodes `master` to be the base reference. While this works on mainline and update release repos, this does not work for projects like Valhalla or Leyden, whose PRs target lworld/premain branches. We can add a new flag to allow customized base reference to adapt to these use cases.
