## Rules

- Do not force visual style.
- Do not choose color, font, or layout taste.
- Do not expand functionality.
- Mark new feature ideas as suggestions.
- Keep Nice-to-have requirements out of the prototype unless the user explicitly asks to visualize them.
- Keep product structure, states, permissions, policy, measurement, and AC visible.
- Keep the Core User Flow visible as 진입과 다음 행동, 사용 규모, and 품질 기준.
