Authentication for the frontend cloud

What this post added

This post details how Clerk has optimized its authentication system for Vercel's frontend cloud architecture. Key contributions include: developing framework-specific SDKs (e.g., for Next.js App Router with RSC support), offering drop-in authentication components like `<SignIn/>` and `<UserProfile/>`, and implementing stateless session management using JWTs for under one millisecond authentication at the edge. It also explains how Clerk facilitates composability through JWT SSO and JWT templates, allowing services to securely identify end-users without relying on traditional secret keys.
