AI Architecture Guide
This blueprint outlines a robust architecture for connecting disparate services within a Next.js 15 ecosystem, leveraging the App Router, React Server Components (RSC), and Server Actions. It utilizes the projected 2026 stable SDK patterns which emphasize zero-bundle-size server logic and end-to-end type safety via advanced TypeScript features.
