Packed Cell Left Entry Under Neighbour

Gallery / Serpentine Layout

A section whose packed cell-mate in the row above is wider has its LEFT entry port sitting under that neighbour's box. A fan-out junction feeding that entry opens its descent in the inter-cell gap beside the source and traverses below the neighbour, rather than descending the crossed column's outer gap and threading the neighbour's interior (issue #1486, vertical descent variant).
