Rail Symmetric Fork Join Spans

Gallery / Off-track & Rails

A `%%metro line_spread: rails` section carrying `%%metro diamond_style: symmetric`, where the fork (BQSR) spans four rails because it also carries the `core` line arriving from upstream while the join (Merge) spans only the three caller rails. Each pill stays centred on the rails it caps, so the two sit 20px apart rather than being forced onto one shared centreline.
