APIView Request-Response Cycle

APIView wraps Django's class-based view with dispatch() that builds a DRF Request (parsed .data instead of raw POST), runs authentication, permission, and throttle checks, then calls the handler named after the HTTP method. Handlers return a Response holding unrendered data that is serialized to bytes late, during content negotiation.
