What is Component boundaries in Laravel, and what role does it play in a real application? In Laravel, component boundaries should be understood as part of a larger application architecture rather than as an isolated API call. A good component exposes a small clear interface instead of coupling the UI element to unrelated application behavior. 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: Blade components provide reusable UI units with attributes, slots and optional component classes, helping keep Blade views modular. The specific focus here is component boundaries: A good component exposes a small clear interface instead of coupling the UI element to unrelated application behavior. 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.
