What is Logout in Laravel, and what role does it play in a real application?

What is Logout in Laravel, and what role does it play in a real application? In Laravel, logout should be understood as part of a larger application architecture rather than as an isolated API call. Logout invalidates the current authentication state and should clear or rotate relevant session information. A strong understanding includes its purpose, the layer where it belongs, the data or request flow it affects, and the situations where another mechanism may be more appropriate. Practical context: Authentication identifies the current user and maintains the authenticated state used by protected application workflows. The specific focus here is logout: Logout invalidates the current authentication state and should clear or rotate relevant session information. This question is designed to test not only terminology, but also how the concept fits into Laravel's request, application, database, security, or deployment workflow.
