Hello from WordPress Playground!

This Playground runs client-side in the browser. It is ready for plugin tests, theme demos, PR reviews, and training without a server.

You are logged in as admin. Settings changes reload this saved browser-backed Playground; temporary Playgrounds warn before reset.
