Welcome to *Python Flask Authentication*! 🚀
In this beginner-friendly series, we’ll build a complete authentication system with:
User Registration (with password hashing)
User Login & Session Management
A Protected Dashboard with `@login_required`
Logout Functionality
Flash Messages for clean feedback

This project is part of my *Flask Auth Series* — small, focused apps that teach you Flask step by step without the overwhelm.
