# React/Next.js Development Workflow

## Overview

Specialized workflow for building React and Next.js 14+ applications with modern patterns including App Router, Server Components, TypeScript, and Tailwind CSS.

## When to Use This Workflow

Use this workflow when:
- Building new React applications
- Creating Next.js 14+ projects with App Router
- Implementing Server Components
- Setting up TypeScript with React
- Styling with Tailwind CSS
- Building full-stack Next.js applications

## Workflow Phases
