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

What is Token revocation in Laravel, and what role does it play in a real application? In Laravel, token revocation should be understood as part of a larger application architecture rather than as an isolated API call. Applications can revoke tokens when a device or client should no longer have access. 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: Laravel Sanctum supports lightweight API token authentication and first-party SPA authentication patterns without requiring a full OAuth server for every use case. The specific focus here is token revocation: Applications can revoke tokens when a device or client should no longer have access. 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.
