  In Poincar\'e-covariant continuum treatments of the three valence-quark
bound-state problem, the force behind dynamical chiral symmetry breaking also
generates nonpointlike, interacting diquark correlations in the nucleon and its
resonances. We detail the impact of these correlations on the
electromagnetically-induced nucleon-$\Delta$ and nucleon-Roper transitions,
providing a flavour-separation of the latter and associated predictions that
can be tested at modern facilities.
