📚 Technical Background (Optional)
A user agent string is a line of text sent in HTTP headers when a browser or device connects to a web server. It typically follows the format defined by various internet standards (RFCs). It provides information such as browser name, version, operating system, and device type. While user agent strings are helpful, they can sometimes be spoofed by bots or privacy-focused browsers.
