The documentation should include:
1. A new section or chapter explaining the purpose and functionality of the script_path feature.
2. Examples demonstrating its implementation for single-page scenarios.
3. Examples showcasing its usage in whole-application contexts.
4. Any configuration or limitations developers need to consider when using the feature.

The expected outcome is comprehensive and easy-to-follow documentation that enables developers to understand and apply the script_path feature seamlessly.
