Fan Bypass Nesting

Gallery / Bypass Routing

A junction fans to a straight continuation, three down-turns into stacked rows, and one far-column bypass. The bypass joins the same concentric corner as the down-turns and descends in the shared channel, peeling into its lane at the inter-row gap rather than grazing the down-turn corners near the junction (issue #652).
