# A ConfigMap is just a bag of key/value data — in this case, a small HTML
# file — that lives in the cluster as its own object, separate from the
# Pod that uses it. We mount it into the nginx container below instead of
# baking the page into a custom container image.
#
# Why this matters for the GitOps story: this is the file you'll edit in
# docs/07-your-first-change.md. Change the text here, commit, push, and
# watch Argo CD notice the difference in Git and push it into the cluster
# for you — no `kubectl` command involved. That's the whole loop, proven
# with one line of HTML.
