  A unified set of predictions for pion and kaon elastic electromagnetic and
gravitational form factors is obtained using a symmetry-preserving truncation
of each relevant quantum field equation. A key part of the study is a
description of salient aspects of the dressed graviton + quark vertices. The
calculations reveal that each meson's mass radius is smaller than its charge
radius, matching available empirical inferences; and meson core pressures are
commensurate with those in neutron stars. The analysis described herein paves
the way for a direct calculation of nucleon gravitational form factors.
