Include part and chapter titles when printing html

Problem

When printing the output to a pdf only contents of the individual markdown files are included. This means that part and chapter titles defined in the summary are excluded from the resulting document.

With chapters this not as big of a problem, because you can simply add the title from the summary to the beginning of the corresponding markdown file manually, although you are still missing the automatic numbering. On the other hand with part titles this problem is much more significant as there are no corresponding files where they could be added.

Proposed Solution

The solution could be to automatically add a headings based on the level of the file and a special type heading for parts when rendering the pdf output. It could also be nice to have the part title optionally on a separate page.

Notes

No response

Start by tracing how the summary and individual Markdown files are converted into HTML and PDF output. Determine how chapter and part heading levels, numbering, and optional page breaks should be represented, then add focused coverage for the resulting rendered document.
