Ported Symmetric Fan Centreline Trunk

Gallery / Fan-out and Fan-in

The same six-branch `diamond_style: symmetric` fan, reached through entry and exit ports from neighbouring sections. The half-pitch centreline the fork and join hubs settle on carries out through the section's own ports and along the single-line trunk either side, so both boundary runs leave as straight risers instead of the upstream trunk sitting a row below the fan it feeds (#1617).
