AI Architecture Guide
This blueprint establishes a high-performance, type-safe connection between Next.js 15 (utilizing React 19 Server Components) and a distributed data persistence layer. It leverages the 2026 'Unified-Transport' pattern, focusing on sub-10ms latency via Edge Runtime compatibility, automated connection pooling, and strict TypeScript schema enforcement. The architecture emphasizes Partial Prerendering (PPR) and Server Actions for a seamless full-stack integration.
