  We describe results for the pion distribution amplitude (PDA) at the
non-perturbative scale $\mu=~$2GeV by projecting the Poincar\'e-covariant
Bethe-Salpeter wave-function onto the light-front and use it to investigate the
ultraviolet behavior of the electromagnetic form factor, $F_\pi(Q^2)$, on the
entire domain of spacelike $Q^2$. The significant dilation of this PDA compared
to the known asymptotic PDA is a signature of dynamical chiral symmetry
breaking (DCSB) on the light front. We investigate the transition region of
$Q^2$ where non-perturbative behavior of constituent-like quarks gives way to
the partonic-like behavior of quantum chromodynamics (QCD). The
non-perturbative approach is based on the Dyson-Schwinger equation (DSE)
framework for continuum investigations in QCD. The leading-order, leading-twist
perturbative QCD result for $Q^2 F_\pi(Q^2)$ underestimates the new DSE
computation by just 15\% on $Q^2\gtrsim 8\,$GeV$^2$, in stark contrast with the
result obtained using the asymptotic PDA.
