Straight Drop Below
A branch fans off at a junction and drops into a section directly below it, in a column that clears both neighbouring boxes. The connecting leg descends as one straight vertical run into the top-entry port rather than leading out to a parallel channel and jogging back onto the port at the section boundary.
