UNNS_ROLE:
Observed post-collapse brightness trajectory.
Type II event with transition-rich decline behavior.
Useful as an intermediate case between plateau-like and more linearly declining
post-collapse regimes.

BOUNDARY_DYNAMICS_INTERPRETATION:
SN 2013ej provides a useful transition object for testing whether light-curve
ladder geometry distinguishes plateau-dominated relaxation from faster
decline-dominated relaxation.
