Part of the fun I have with this is figuring out how to build a simple application in as little time as possible that's still useful from day 1 -- and after some thinking I figured it out.
So v0.1 will have a GUI only for the primary use case: reading things. It'll eventually be multi-user (schema is set up for it), but single-user upon release. And to do anything besides the primary use case, you'll use cURL or Postman or whatever to call the API.
