This Python script demonstrates the FastCampus AI Agent & Vibe Coding methodology by:
1. Creating a modular class that inherits from FastCampusAgent
2. Implementing three core functions (data fetching, formatting, email distribution)
3. Including comprehensive error handling and logging
4. Using environment variables for configuration
5. Following Python best practices with type hints and docstrings

The script can be scheduled to run weekly using cron or FastCampus's automation scheduler. The logging ensures any issues are immediately visible, and the modular structure allows for easy extension to include additional metrics or recipients.
