We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Show banner throughout application when "live demo mode" is turned on.
We should show a banner at the top of the screen on all pages that explains that Mathesar is in live demo mode and that each session has its own copy of demo data and that data will be deleted regularly.

Assigning this to @mathemancer to make sure it gets implemented at some point, @ghislaineguerin for the design, and @pavish for the frontend.

--- END ISSUE ---
