A solved network, written out so a person can read it.
The pressure ladder is the answer to the question that started this project:
where does the pressure actually go between the tank and the injector. It lists
every component in flow order with what it cost, so the largest loss is
obvious rather than inferred.
Two things are always printed, whether or not anyone asked:
* **Mass conservation.** A converged solve that does not conserve mass has
found the wrong answer confidently, and that is exactly the failure that
looks like success.
* **Assumed parameters and violated limits.** A number resting on twelve
library defaults is a different claim from one resting on twelve
measurements, and the difference should never be invisible.
