Indeed, this is the direction I'm heading. However, I'm doing it by
hand first so I can refine my methods to a point I'm satisfied with,
and then build the automation afterwards, hopefully doing it right the
first time. I place value on this because I plan to stick with the same
style throughout all my code so that I can read and reuse my own code 30
years from now and not have to think about how much I hate past me.

The sort of information I'm after answers questions similar to and
including, "Why put this typeclass in this source file and not that
one?" and "Should I put all my type signatures, typeclasses and data
structures at the top? At the bottom? Should I put them in a separate
source file?"

Having outside perspectives from actual people that I'm having
conversations with will help me both learn the finer points of the
topic (from actual programmers) and piece together a strategy I'm happy

Your code is a pleasure to read; I shall enjoy studying it. :-)
