This script is designed to enhance website accessibility by enabling a high-contrast display mode based on user preference. It typically interacts with browser storage mechanisms (like cookies or local storage) to remember a user's choice regarding this mode across sessions. Additionally, its name suggests it plays a role in managing cookie consent, potentially displaying a consent banner, recording user consent decisions, and enforcing cookie policies. It likely applies CSS changes dynamically to the webpage to switch between standard and high-contrast visuals, improving readability for users with specific visual impairments or preferences. Its behavior on a browser involves listening for user interactions (e.g., clicking a 'high contrast' toggle or a cookie consent button), reading from and writing to browser storage, and applying visual styling changes. The script ensures that these accessibility and privacy choices are persistent for the user.
