Module kinds 

The prompt kinds: one behavioural module per question type.

Each kind implements the same question three ways from one place:

• non-interactive — resolve to the declared default or return a typed error, without touching the terminal;
• line-driven — print a numbered list (or plain prompt) once and parse a typed answer, re-asking on invalid input;
• key-driven — draw a live frame and update it in place as arrow keys move focus and space toggles selection.

A kind chooses the interactive path by inspecting Terminal::capabilities, so the prompter never branches on a concrete terminal type.
