UI/UX Path Forward When Data Cannot Be Obtained

In some cases, no matter how hard we try, a component or interface may not be able to ascertain the Manifest or Canvas data. Interfaces often need this data for the interface to be useful at all. In interfaces like this, users see an error and a dead page.

We want to improve that experience, especially when it pertains the Manifest, Canvas, or Image data that may be changed outside of our purview and control. We desire a graceful UI/UX so users have a path forward even without this data.

We should also consider what should happen when critical page URL are missing, such as `projectID=` and `pageID=`. In most instances users only see a header, footer, and blank blue background where a page should be.

## Interfaces to Consider

- /project
