Covers color contrast detection and fixing, visual impairment simulators (color blindness, blurred vision, dyslexia), page structure and heading outlines, keyboard/focus order analysis, ARIA attribute validation, readability scoring, element sizing checks, responsive design overflow detection, and media query testing for dark mode, reduced motion, and forced colors.
