🚀 Features

🔐 User Authentication

• Secure user registration with password hashing (using Werkzeug)
• Login and logout with session management via Flask-Login
• Input validation and error handling for duplicate emails, short passwords, and missing fields
• Session cookies and login state tracking implemented via Flask’s HTTP request–response cycle

📓 Note Management (CRUD)

• Create, view, edit, and delete notes tied to each logged-in user
• Notes are stored persistently in a relational database
• Authenticated access ensures users only see and modify their own notes

🌐 Full-Stack Architecture

• Backend powered by Flask and SQLAlchemy ORM for database operations
• Frontend built with HTML, CSS, and templating via Jinja2
• Client-server communication follows the HTTP protocol: GET for rendering pages, POST for form submissions

🧠 Error Handling

• Displays user-friendly error messages for login, sign-up, and note validation failures
• Backend checks ensure empty notes are not accepted and accounts are not duplicated
• Flash messages provide real-time feedback on user actions

🛡️ Security Highlights

• Passwords stored securely using one-way hashing (not in plain text)
• Login-protected routes prevent unauthorized access
• CSRF-safe form handling with built-in Flask tools
