Junction Entry Reversed Fold

Gallery / Merge & Convergence

A two-line bundle exits a TB section's RIGHT side, wraps into a Source section, then fans out at a junction into two same-row destinations. The bundle order is carried concentrically through the reversal corners so the lines never cross at a station, and the fan-out peels off cleanly (issue #760).
