   Component — the four view states
   -------------------------------------------------------------------------
   Every view that fetches renders ALL FOUR: loading, empty, error, forbidden.
   (The sign-in form is not such a view — see FRONTEND_STRUCTURE.md.) A 403 is
   shown AS a 403 — never as an empty list, because "no permission" and "no
   data" look identical once they collapse into the same empty state, and the
   permission bug then hides forever.
