This issue is the scheduling surface for the post. It stays open until the post
publishes — merging the PR does not close it.

Editorial commands (write access required)

Comment one of these here (they take effect once the PR is merged):

/schedule 2026-MM-DDTHH:MM:SSZ   # queue for a publish time (UTC)
/publish-now                     # publish immediately
/hold                            # keep drafted, no publish time
/cancel                          # drop a pending schedule

Scheduling writes docs/blog/.schedule.yml on main, so /schedule only
takes effect once the post file exists on main (i.e. after the PR merges).
