Adafruit CSI or DSI Cable Adapter Thingy for Raspberry Pi

Every time someone posts on the Adafruit forums and says they wish they had a way to adapt between the 15-pin 1mm pitch Camera (CSI) or Display (DSI) connectors on big Raspberry Pi computers and the 22-pin 0.5mm pitch connectors on Pi Zero and CM4 Dev boards, we say, "Oh you mean like some sort of CSI/DSI cable adapter thingy? Yeah, we don't have one of those in stock yet" But that time is over! Now we can say, "Yes, we have a CSI/DSI Cable Adapter Thingy in stock!" And we point them here.
