It'd be nice for a user that's browsing an embedded Playground block to have a way to get details about the embedded block. Such details might include:

• The Playground URL
• Read-only details regarding the PHP version, WP version, etc.

Maybe even a rudimentary read-only(?) version of the regular Playground toolbar:
