Stacked Right Ports Coincident
A RIGHT exit and its target's RIGHT entry stacked in one grid column pin to the shared column-edge X; the feed bows out into the descent channel past the port with outward corner curves, and a co-terminating feed shares that channel rather than running a separate parallel vertical.
