• POST /api/login - Authenticate user
• POST /api/register - Create new user account
• POST /api/logout - End user session
• GET /api/auth - Check authentication status

The app uses SQLite with a simple users table:

CREATE TABLE login_users_1 (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  username TEXT UNIQUE NOT NULL,
  password TEXT NOT NULL,
  created_at DATETIME DEFAULT CURRENT_TIMESTAMP
);

• HTTP-only cookies for session management
• Secure cookie settings
• Input validation
• SQL injection protection with parameterized queries
• Password length requirements

1. Visit the login page
2. Use demo credentials or create a new account
3. Access the protected dashboard after authentication
4. Sign out to return to the login page

• Frontend: React 18, TailwindCSS
• Backend: Hono, SQLite
