Why is Attachments important in Laravel applications, and what problem does it solve for developers? The key reason to understand attachments is that Laravel applications are usually composed of several layers that must work together predictably. Mailables can include supported file attachments when the application needs invoices or documents. Ignoring that boundary can lead to duplicated logic, poor security, unnecessary database work, or code that is difficult to test. Why it matters in practice: Laravel mail features provide a structured way to create and send application emails using configurable mail transports and templates. The specific focus here is attachments: Mailables can include supported file attachments when the application needs invoices or documents. 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.
