Symmetric Multiline Merge Median

Gallery / Fan-out and Fan-in

Three metro lines on distinct tracks converging on one shared station under `diamond_style: symmetric`. The merge anchors on the median feeder track (the middle line) rather than the first-declared line's extreme track, so each feeder bends toward it by the least amount (#1277).
