It describes same-day cleanup — ASG=0, delete ALB/NAT if unused, release EIP, delete idle EBS/EFS, empty unused ECR. The how-to section notes keep a short checklist in every lab README; verify Cost Explorer next morning. An example on the card is morning bill shows near-zero for the lab account after checklist.
