<article> / Card Before you ship
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 Card to solve this user need without losing the current context. User context: A project card shows a picture, title, update time, owner, and more-actions menu. Recommended pattern: Card. Why it fits: Use cards when each item must be easy to scan or reorder. Do not use it when: Never put every section in a floating box when those sections do not need grouping. 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): No single official standard controls the whole term. Its meaning may change across teams, platforms, or frameworks. Unknowns to confirm: Product wording, data source, analytics events, supported devices and languages, and platform limits.
