AI Architecture Guide
An architectural framework for establishing a secure, type-safe bridge between abstract service entities within a Next.js 15 (React 19) environment. This pattern leverages the 'use server' directive for secure SDK execution and React Server Components (RSC) for streaming data transfer with minimal client-side hydration overhead.
