AI Architecture Guide
This blueprint establishes a high-performance, type-safe integration between a Next.js 15 App Router application and an external service layer using the 2026 stable React Server Components (RSC) architecture. It leverages the standard 'use server' directive for secure, zero-API-latency data mutations and the 'use cache' directive for optimized data retrieval.
