Before release, check the page structure, keyboard access, visible focus, contrast, and zoom. Also check loading, empty, error, success, cancel, and reduced-motion states.
Outcome: Use Accordion to solve this user need without losing the current context. User context: An FAQ shows the questions first. A person can open an answer without leaving the page. Recommended pattern: Accordion. Why it fits: Use it for optional sections that each have a clear, separate heading. Do not use it when: Never hide short, essential information only to make the page look neat. 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): It is official for that source. Other platforms or teams may use the term in another way. Unknowns to confirm: Product wording, data source, analytics events, supported devices and languages, and platform limits.
