 Via middleware, Pan injects a simple JavaScript library into your HTML pages. This library listens to events like `viewed`, `clicked`, or `hovered` and sends the data to your Laravel application. Note that this library does not collect any personal information; such as IP addresses, user agents, or any information that could be used to identify a user.
