    summary:
        'The NumberInput component demonstrates strong compliance with WCAG 2.0, 2.1, and 2.2 standards at Level A and AA. Critical accessibility features are implemented including proper label association, keyboard navigation, error identification, ARIA attributes, focus management, and accessible numeric steppers. The component uses semantic HTML (<input type="number">), unique IDs for label/error associations, aria-describedby for linking hints and errors, and aria-label for stepper controls. Some contrast ratios require manual verification. 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 include 2.1.3 Keyboard (No Exception), 3.2.5 Change on Request, and 1.4.8 Visual Presentation. Non-compliant AAA criteria include 1.4.6 Contrast (Enhanced), which requires a 7:1 contrast ratio. To achieve full AAA compliance, text and border colors need to be adjusted to meet 7:1 contrast ratio (currently designed for AA standard of 4.5:1).',
