"""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.

"""Classic inpainting restorer (cv2) — the always-available baseline.
HONEST LIMITATION: cv2 inpainting fills the masked region by propagating
surrounding pixels. It removes the mosaic/bar but does NOT reconstruct the hidden
detail — it smooths/guesses. For real reconstruction a generative model
(DeepMosaics / LADA) is needed; this is the no-weights, no-GPU fallback so the
"Расцензурить кадр" flow works end-to-end today.
