  We compute the asymptotic safety landscape stemming from ultraviolet-complete
photon-graviton flows in a field theoretic setup, and we confront it with the
weak gravity conjecture and, for the first time, with positivity bounds. At
fourth order in derivatives, we find two gravitational fixed points providing
viable ultraviolet completions for the theory. One of them comes with a single
relevant direction, which sets the scale of quantum gravity. The corresponding
sub-landscape is a single point. The second fixed point yields a richer
sub-landscape of effective theories, most of which is described by an
approximately straight line in the space of dimensionless Wilson coefficients.
We additionally discover that: (i) the two sub-landscapes are continuously
connected via a small "candy cane" regime, and the whole asymptotic safety
landscape falls onto a plane; this is consistent with earlier findings and
could be a universal feature in Asymptotic Safety; (ii) in such a
field-theoretic setup, the Euler coupling plays a special role, as it is
unconstrained by quantum scale invariance, but can enter off-shell bounds such
as entropy-based positivity constraints; (iii) Planck-scale-suppressed
violations of both weak gravity and positivity bounds occur across the
landscape. The latter result resonates with expectations grounded on effective
field theory arguments.
