When refresh url which is not ending with /stories - redirect to default repo happens

This issue has no description.

The issue title suggests a routing bug where refreshing a URL not ending with '/stories' causes a redirect to a default repository. Start by examining the Elm application's routing setup, likely in a file like `src/Router.elm` or `src/Main.elm`. Look for route definitions and redirect logic. Check how URL parsing and navigation are handled, and test the behavior by running the app and refreshing different URLs.
