Does work on this branch build upon your work in ingest-scp? If so, change the base branch to ingest-scp. If not, let's talk about how to make sure you're not duplicating changes across PRs. Once we establish the base branch for this PR I will give more specific comments.

I like the Hutch theming! The dream of Oncarto is that anyone could grab this and spin it up for their own cancer center. I think we should separate out the Hutch theming so that the version we run here has it, but we don't force it on everyone else. Let's try to think about this creatively so that other people can look at the Hutch theming as an example for their own theming. Like can we boil the theming down to a function that we drop into the app? Or as an argument to oncarto::run_app()? Once we figure out the PR base I will have more specific suggestions.

Talking to Vivek live right now! He's rightfully concerned that folks won't notice the map has changed, we should consult @codebeaker about whether we should have a loading spinner, a toast, or related to make the change apparent.
