The $(A{+}1)$-body Schr\\\"odinger equation is solved with a neural-network variational Monte Carlo framework, generalized to incorporate mesonic degrees of freedom. Benchmarking on light nuclei from $^2$H to $^{12}$C yields ground-state energies consistent with experiment. Meson-nucleus bound states emerge at $A\\ge2$ for $\\phi$, $A\\ge4$ for $J/\\psi$, and $A\\ge6$ for $\\eta_c$.
