The concept of integrating styling directly within a Markdown document for testing purposes is indeed helpful. I appreciate your guidance on this. Additionally, the ability to include multiple files with stylesheet codes for various purposes through transclusion is extremely beneficial. For example, using {{numberedheadings.md}} and {{largerheadings.md}} allows for easy adjustment of the current document’s style with pre-formatted styles as needed. This approach enables the use of a customized stylesheet while incorporating special formatting when necessary.
