This script is designed to detect and apply user preferences regarding high contrast display settings. It likely stores the user's choice, potentially in a cookie, to ensure the preference persists across sessions or page loads. By doing so, it contributes to the website's accessibility features, allowing users with visual impairments or specific needs to experience content in their preferred high contrast mode. It operates client-side, typically modifying CSS styles or adding specific classes to the document body to trigger the high contrast visual theme. The script ensures a consistent user experience by remembering accessibility choices and applying them automatically.
