Outcome: Use Web Notification to solve this user need without losing the current context. User context: A user has chosen to receive a reminder for an event starting in ten minutes. One translated notification names the event and opens the right details when clicked. Ask for permission only after explaining the value, and keep normal page feedback on the page. Recommended pattern: Web Notification. Why it fits: Use this term for permitted, time-sensitive information that is still useful when the page is not open. Do not use it when: Do not send marketing by default, repeat page status, or send a notification with no clear place to open. 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.
