FYI for any new or casual Mermaid users, it comes with a built-in alternate layout called `elk` that I find does a much cleaner job on complex flowcharts.

You can try it with Line9's first chart: https://mermaid.ai/live/edit#pako:eNpVVEtv2zAM_iuCTilgB1mbxq...
While it's nice and compact, it actually is rougher to grep.
Excellent work on Line9 BTW, it looks fantastic. :-)
