Looks good, works in UI 👍

Should we add some generic way how a page would hook in so that when navigations a custom page-specific check would get executed?

Rather than adding these things globally?

Thoughts, @Hyperkid123, @himdel, @rvsia ?

I would wait and add it to the "screen" definition once we have frontend routing.
(Assuming there won't be a new kind of forms that would benefit from it now.)
