AI Architecture Guide

This blueprint outlines the architectural integration between Next.js 15 (utilizing React Server Components and Server Actions) and a distributed persistence layer. It focuses on type-safe data fetching, zero-bundle-size logic, and leveraging the 2026 stable specification for asynchronous request handling in a serverless-first environment.
