Outcome: Use Textarea to solve this user need without losing the current context. User context: A feedback form gives people enough visible space to explain a problem in detail. Recommended pattern: Textarea. Why it fits: Use it for longer messages, notes, descriptions, or text that looks like code. Do not use it when: Never put structured data in one large box when separate fields would make each answer clearer. 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.

Release checks: Give each field a label that code can read. Link hints and errors, and keep entered values.

Before changing code, report the evidence you found, gaps, severity, and the smallest safe fix.
