Design principles
Let the structure explain the intent.
Principles I value when building tools that can evolve.
Make intent visible through types
I prefer TypeScript for application code and explicit types at input and result boundaries.
Keep responsibilities focused
I aim for handwritten files under 120 lines, split by understandable responsibility. I do not compress code to satisfy a line count; generated and third-party code have separate constraints. This is a preference, not a claim that every existing file meets it.
