Trajectory logic flow diagram

At the time of developing this game I used sheets of paper to draw out the logical flow. I briefly tried to use Draw.io but found it so onerous that I soon gave up. Since then I have discovered Mermaid diagramming, and charting the finished trajectory logic from this game was an interesting exercise: https://github.com/patters-match/artillery/blob/main/trajectory_loop.md

I can remember during development that every time I thought I saw a potential optimization in this logic I would break some corner case. If it ain't broke...
