-"""Resource-bound contract for the image re-encoder subprocess.
-
-Rejection of oversized or bomb-shaped images must happen from the container
-header, before any full pixel decode, so a hostile upload cannot allocate
-hundreds of megabytes inside a 512 MiB service. Decompression-bomb warnings are
-treated as errors: a warning that still returns pixels is not a rejection.
-
-Peak RSS is measured per child with os.wait4, so each measurement belongs to
-exactly one subprocess rather than a running maximum.
