Working around an off-by-4 is not what I had on my agenda for a 🌞🫠 evening:

>>> pcap[0].load.splitlines()[-2]
b'Content-Length: 237992'
>>> sum([len(p.load) for p in pcap[1:]])
237996

It took me quite a while of printf debugging within #flask #werkzeug to realize that it was not the multipart-handler chomping off the last bytes of the boundary, but the WB2200F sending an incorrect length.
