build-frontend

Build or modify frontend interfaces using repository-native components while preserving accessibility, responsive behavior, state handling, and visual verification. Use for UI features, design implementation, forms, client-side defects, and frontend refactors; do not use for backend-only or infrastructure-only work.

# Build Frontend

## Domain contract

- Preserve the project’s framework, styling system, and component conventions.
- Do not invent API response fields or silently change backend contracts.
- Do not replace an established design system with custom one-off styling.
- Define loading, empty, error, success, and disabled states that the changed
  flow can reach.
- Keep semantic HTML, keyboard navigation, focus behavior, labels, and contrast in scope.
- Avoid speculative shared abstractions for a single component.
- Treat screenshots and mockups as visual references, not proof of interaction behavior.
- Do not claim visual verification unless the UI was rendered or inspected.
