# **IMPORTANT:** Do not change the FREEZE environment variable set here!
# This workflow runs on a recurring basis. To temporarily disable it (e.g.,
# during a docs deployment freeze), add an Actions Secret to the repo settings
# called `FREEZE` with a value of `true`. To re-enable workflow, simply
# delete that Secret from the repo settings. The environment variable here
# will duplicate that Secret's value for later evaluation.
