Coding Rules and Instructions

1. Test-Driven Development (TDD) with pytest: Always write a failing test before writing implementation code (Red-Green-Refactor). Use pytest and pytest-fixtures for test setup, execution, and teardown.
2. KISS (Keep It Simple, Stupid): Favor the simplest solution that meets the requirements.
3. DRY (Don't Repeat Yourself): Avoid code duplication. Extract reusable logic into functions or classes.
4. Standard Libraries and Tools: Utilize standard Python libraries (like datetime for date/time, requests for HTTP requests, and logging) and external libraries, including BeautifulSoup4 for HTML parsing, to avoid reinventing the wheel. Favor well-maintained and widely-used libraries.
5. YAGNI (You Ain't Gonna Need It): Don't implement features or functionality unless they are currently required.
6. SOLID Principles & Extensibility: Adhere to SOLID principles, promoting maintainability, testability, and future extension. Consider potential future requi
