Documentation

Excerpt

A prototype is throwaway code that answers a question. The question decides the shape.

Identify which question is being answered — from the user's prompt, the surrounding code, or by asking if the user is around:

"Does this logic / state model feel right?" → LOGIC.md. Build a tiny interactive terminal app that pushes the state machine through cases that are hard to reason about on paper.
"What should this look like?" → UI.md. Generate several radically different UI variations behind a single entry point, switchable at runtime.

This is the opening of the README. Read the full README on GitHub.
