Task: a recursively nested ZIP bomb (~1014 levels), each level holding a 1MB 'a'-filled decoy plus the next inner zip. Solution: descend the nesting safely in memory with Python zipfile+BytesIO and concatenate the decoy filenames across all levels — the filenames spell a paragraph ending with the flag.
