Burn opaque BLACK rectangles into an image, destroying the underlying pixels.
Boxes are percent (0-100) of the natural image; each is converted to a clamped pixel rect and composited as a filled black overlay. Unlike an annotation overlay (coordinates on a URL fragment), this is DESTRUCTIVE by design — a redacted region can never be recovered from the stored asset. Degenerate boxes (sub-pixel or off-canvas) are skipped. No boxes → the original buffer is returned untouched (no re-encode).
