# Full-Stack Evolution Instructions
I am passing you a frontend React component. You must convert it into a production-ready Next.js 14+ client/server component architecture.
1. SEPARATION OF CONCERNS: Extract the data validation logic into a separate Zod schema file.
2. SERVER ACTIONS: Convert any dummy 'onSubmit' handlers into Next.js Server Actions using 'use server'.
3. ERROR HANDLING: Return standardized error objects { error: string, success: boolean } instead of throwing raw 500 exceptions to the client.
4. STATE: If loading states are required, implement React's 'useFormStatus' gracefully.
5. Do not modify the existing Tailwind classes unless fixing a responsive bug.
