    - Naming Conventions: PascalCase for classes, methods, properties; camelCase for local variables and parameters.
    - Formatting: Consistent indentation, brace placement, and spacing.
    - Commenting: Clear and concise comments for complex logic, public APIs, and important decisions.
  Benefits: Improved readability, easier collaboration, reduced bugs, and enhanced maintainability.
  Example (Conceptual):
    // Method to calculate player score
    public int CalculatePlayerScore(int baseScore, int bonusPoints)
    {
        int totalScore = baseScore + bonusPoints;
        return totalScore;
