Prototype

A prototype answers one question. It is not production code.

Shape

Pick the smallest artifact that lets the user judge the idea:

• Logic, state, API shape, or workflow: make a tiny runnable CLI, script, or local page that exposes the state and lets the user push it through cases.
• UI or interaction: make 2-4 meaningfully different variants, preferably inside the existing page or route they would affect.

If the question is unclear, state the assumption before building.
