+"""Restorer interface — "un-censor" detected regions of an image.
+
+A Restorer takes an image plus the detected censored regions and returns a new
+image with those regions reconstructed/filled. This mirrors the ``Detector``
+abstraction so different engines (classic inpaint now; a generative model like
+DeepMosaics / LADA later) plug in behind the same interface.
