+# Copy to kc-lab.yaml and fill the two placeholders. The real file is ignored by
+# git because plain_text_passwd is a credential, however disposable.
+#
+# Indentation is spaces only. YAML forbids tabs, and cloud-init fails silently
+# on a parse error: the guest boots as "localhost" with no user and no way in.
