Force Strong Password Notice

How can you force strong password notice in WordPress? This use case shows how a focused WordPress code snippet can handle the task without installing a heavy plugin. The snippet should show an admin notice when a user profile has weak password settings and produce this result: Admins see a warning encouraging strong passwords for accounts. You can also log in to LeonLab.ai, describe this WordPress use case in plain English, generate the snippet, review the PHP code, and deploy it to the selected WordPress project.
