AI Architecture Guide
Architectural blueprint for integrating Next.js 15 App Router with Supabase (v2026 SDK Spec) using the decoupled Server-Side Client pattern. This approach leverages the asynchronous 'cookies' and 'headers' APIs introduced in Next.js 15 to ensure thread-safe authentication and real-time database syncing within the React Server Components (RSC) architecture.
