  A novel method is employed to compute the pion electromagnetic form factor,
F_\pi(Q^2), on the entire domain of spacelike momentum transfer using the
Dyson-Schwinger equation (DSE) framework in quantum chromodynamics (QCD). The
DSE architecture unifies this prediction with that of the pion's valence-quark
parton distribution amplitude (PDA). Using this PDA, the leading-order,
leading-twist perturbative QCD result for Q^2 F_\pi(Q^2) underestimates the
full computation by just 15% on Q^2>~8GeV^2, in stark contrast with the result
obtained using the asymptotic PDA. The analysis shows that hard contributions
to the pion form factor dominate for Q^2>~8GeV^2 but, even so, the magnitude of
Q^2 F_\pi(Q^2) reflects the scale of dynamical chiral symmetry breaking, a
pivotal emergent phenomenon in the Standard Model.
