AI Architecture Guide
This blueprint establishes a high-performance, type-safe connection between Next.js 15 (App Router) and a distributed PostgreSQL instance using Prisma v7.0.0 (2026 Stable). The architecture utilizes React 19 Server Actions for data mutations and the 'use cache' directive for optimized edge-side data fetching, ensuring minimal latency and type-safe end-to-end communication.
