Same Line Fan Distinct Descent

Gallery / Bypass Routing

A source fans two same-line branches plus a distinct-line branch down into the rows below while a third line carries straight on. Red and green descend as one per-line bundle - the two red branches share a single fused track and green sits one step beside it - peeling off one branch at a time, rather than the red splitting into two parallel same-colour strokes (issue #1409).
