The issue identifies the client group and the NavBar and FishBoard guide feature, but no files or tests. Start by locating the NavBar and FishBoard entry points in the client code, then clarify the expected guide window and the behavior of the “do not show again” checkbox. Done means both TODO items work as described and the existing client checks pass.
