Near Vertical Junction Hook

Gallery / Inter-section Routing

A fan-out junction overhanging a same-column RIGHT entry one row below. The two-line bundle drops straight down the junction's own column and turns once into the port, rather than leading out to a centred gap channel and hooking back: a hook's opposite-handed corners cannot nest a multi-line bundle. The destination section carries the matching line order so the bundle arrives in the order the section lays it out (#1018).
