Return ni:/// URIs (or, optionally, /.well-known/ni/ paths) for media. Provide a helper to serve the .well-known paths from a service worker. No more option to get media URIs from the persistence layer, instead each layer will provide a fit-for-platform mechanism to map ni URIs to data, file paths, whatever make sense in context. For web that's Response object or service worker interception. Avatars are now two-part: the possible-null ni URI and the never-null placeholder. Display the placeholder while loading the real avatar data, or if it is null or loading it fails for any reason.
