Manual Rl Row Nonconsumer Bypass

Gallery / Serpentine Layout

A manual-grid serpentine whose return row flows right to left via direction: RL. A non-consumer line shares an exit bundle with a consumed line but is not consumed by the intervening RL section, so it must bypass around that section rather than route through its interior. The descent column lands in the clear gap beside the intervening box and the line loops below the whole row into its target (issue #1211).
