UNNS_ROLE:
Second observed post-collapse brightness trajectory.
Transition-rich core-collapse light-curve object.
Useful as a Type IIb / envelope-stripping comparison case against SN 1987A.

BOUNDARY_DYNAMICS_INTERPRETATION:
SN 1993J provides a structured post-collapse brightness-time record with strong
rise, peak, decline, and transition behavior. It is useful for comparing
observable relaxation in a stripped-envelope core-collapse event.
