  text: A growing number of core-collapse supernovae (CCSNe) exhibit diverse light-curve
    morphologies that indicate strong interactions with dense, pre-existing circumstellar
    material (CSM). Understanding the physical origin of such CSM is essential for
    exploring the late-stage evolution of SN progenitors and the diversity of observed
    transients. Non-conservative mass transfer during binary interactions provides
    a promising channel for producing dense CSM before core collapse. Using the stellar
    evolution code MESA, we simulate post-common-envelope binaries that give rise
    to ultra-stripped progenitors before core collapse, and self-consistently construct
    the CSM from the mass loss during binary evolution. We further analytically predict
    the resulting bolometric and radio light curves by following the shock dynamics
    of SN ejecta interacting with the CSM. We find that surface-radius variations
    in the ultra-stripped progenitors, which reflect changes in core energy generation
    after a delay comparable to the thermal timescale, trigger multiple episodes of
    mass transfer and give rise to a variety of CSM density profiles, including detached
    shells and multi-peaked structures. When interacting with SN ejecta, such CSMs
    give rise to non-monotonic, multi-peaked optical and radio light curves that qualitatively
    resemble features observed in some stripped-envelope SNe. Future long-term multi-wavelength
    monitoring of ultra-stripped SN candidates, particularly at late times, will be
    crucial for probing structured CSM and constraining the long-term mass-loss history
    of stripped progenitors prior to core collapse. Our results suggest that SN-CSM
    interaction in binaries hosting ultra-stripped progenitors can provide a possible
    channel for producing diverse light-curve morphologies, highlighting a potential
    connection between the pre-SN evolution of massive binary stars and the diversity
    of their explosive transients.
