    summary:
        'The Button component demonstrates strong compliance with WCAG 2.1 Level AA standards. Most critical accessibility features are implemented including keyboard navigation, screen reader support, focus management, and proper ARIA attributes. Some contrast ratios require verification, and certain criteria depend on application context. This report evaluates criteria from WCAG 2.0, 2.1, and 2.2 guidelines. The component fully meets Level A requirements, fully meets Level AA requirements (with some items requiring verification), and partially meets Level AAA requirements. 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, 2.5.5 Target Size - Small/Medium buttons and Large at lg breakpoint need 44x44px minimum. To achieve full AAA compliance, Small and Medium button sizes need to be increased to 44x44px minimum, and contrast ratios need to meet AAA standard of 7:1 (currently designed for AA standard of 4.5:1).',
