What is Route groups and prefixes in Laravel, and what role does it play in a real application? In Laravel, route groups and prefixes should be understood as part of a larger application architecture rather than as an isolated API call. Groups can automatically apply name prefixes to related routes. 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: Named routes give routes stable application names that can be used by helpers such as route() and redirects instead of hard-coded URLs. The specific focus here is route groups and prefixes: Groups can automatically apply name prefixes to related routes. 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.
