Using $10,\!080^3$ grid simulations, we analyze scale-dependent alignment in
driven, compressible, no net-flux magnetohydrodynamic turbulence. The plasma
self-organizes into localized, strongly aligned regions. Alignment spans all
primitive variables and their curls. Contrary to incompressible theory,
velocity-magnetic alignment scales as $\theta(\Lambda) \sim \lambda^{1/8}$,
where $\lambda$ is the scale, suggesting a distinct three-dimensional eddy
anisotropy and a much higher critical transition scale toward a
reconnection-mediated cascade.
