Give assistive tools the control’s name (accessible name), purpose (role), value, and state. Check keyboard use, visible focus, target size, disabled and busy states, feedback, and recovery.
Outcome: Use Radio Group to solve this user need without losing the current context. User context: For delivery, the choices are standard, express, or pickup, and only one can be active. Recommended pattern: Radio Group. Why it fits: Use it when there are only a few choices and seeing them all helps people decide. Do not use it when: Never use it for a long list or when choosing nothing is often allowed. Product requirements: Define the default, loading, empty, error, success, and recovery states. Keep user input. Give clear feedback after every action. Accessibility and resilience: Use semantic HTML, full keyboard access, and visible focus. Make the layout work when zoomed and support reduced motion. Follow the project’s current rules. Do not add a new UI library unless the project already uses it. Acceptance criteria: The main task works with keyboard only and at 320px width. Focus and status changes are announced. Check loading, failure, retry, cancel, and reduced-motion paths. Evidence and limits (evidence boundary): The standard covers only the listed scope. It does not choose the visual style, product decision, or Vibulary example. Unknowns to confirm: Product wording, data source, analytics events, supported devices and languages, and platform limits.
