    summary:
        'The Switch component demonstrates strong compliance with WCAG 2.1 Level AA standards. Built on semantic HTML button element with role="switch", it provides comprehensive accessibility features including keyboard navigation, screen reader support, proper ARIA attributes (aria-checked, aria-required, aria-invalid, aria-describedby, aria-disabled), and label association via htmlFor/id. The component fully meets Level A requirements (15/15 criteria compliant), fully meets Level AA requirements (8/8 criteria compliant, with 3 items marked as "unsure" requiring manual verification: 1.4.3 Contrast, 1.4.11 Non-text Contrast, 2.4.7 Focus Visible), and partially meets Level AAA requirements (4 out of 9 applicable criteria compliant). Currently compliant AAA criteria: 1.4.8 Visual Presentation, 1.4.9 Images of Text, 2.1.3 Keyboard (No Exception), 3.2.5 Change on Request. Non-compliant AAA criteria: 1.4.6 Contrast (Enhanced) - requires 7:1 contrast ratio (currently designed for AA 4.5:1), 2.5.5 Target Size (WCAG 2.5.8) - Small (18px height at sm, 12px at lg) and Medium (20px height at sm, 16px at lg) switches need 44x44px minimum interactive area. Application-dependent AAA criteria: 3.3.6 Error Prevention (All) - requires application-level confirmation patterns. Not applicable AAA criteria: 2.2.3 No Timing, 2.2.4 Interruptions. To achieve full AAA compliance, Small and Medium switch sizes need touch target extension to 44x44px minimum, and contrast ratios need to meet AAA standard of 7:1. IMPORTANT: Items marked as "unsure" require manual verification using contrast checker tools and screen readers.',
