Hide Help Tabs

How can you hide help tabs in WordPress? This use case shows how a focused WordPress code snippet can handle the task without installing a heavy plugin. The snippet should remove the Help tab from admin screens and produce this result: The Help dropdown is hidden on all wp-admin screens. 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.
