Project mode, when enabled, runs the appview rooted at a specific project user like project.org. This removes the usual user-scoped routing that exists on the production appview. For example, if the custom appview is running at code.project.org: code.project.org/project.org/example-repo -> code.project.org/example-repo Signups (done via our PDS) are disabled.
