Current projects still share a builder pattern

Quick work-in-progress note: the public pages around my current projects still point to the same builder pattern I've been pushing on.

Right now that includes GitHub repositories, Ray GitHub repository, and Geometra GitHub repository. Each one gives a different angle on the same habit: make the work concrete enough that someone else can inspect it, try it, or understand where it is headed.

The repositories are useful because they show the implementation choices, not just the finished positioning.

It is still work in progress, but the shape is getting easier to see from the outside.
