    summary:
        'The ChatInput component demonstrates strong compliance with WCAG 2.1 Level AA standards. The component implements comprehensive keyboard navigation, proper ARIA attributes, screen reader support, focus management, and accessible value announcements. The textarea uses proper labeling with aria-label and aria-describedby. File attachments are properly labeled with aria-label attributes and support Delete/Backspace keys for removal. Top queries support full keyboard navigation with arrow keys, Enter/Space, Home/End, and Escape. Character count is available via aria-describedby when maxLength is provided. The component uses semantic HTML and proper roles (region, listbox, option, toolbar). Some contrast ratios may require verification depending on implementation context.',
