Notes

Conversion is good enough to reproduce the original intended content, but it does not worry about factors like list bullets / numbers. As a result, output from a null configuration ({}), will not be identical to the input, but what's the point of a null configuration?
Block styles are generally applied to outermost blocks only, except for the figure style (if enabled), which will be applied to figure list item paragraphs.
Table style works but is broken in pandoc versions greater than 2.7.1 (see jgm/pandoc#6496).
So-called "double styles" (emphasis_strong, strong_emphasis, and strong_code) each require the base styles also be defined.
Never define a single style name to be used by both blocks and spans! If you do and a document uses it, there will be conflicts later in the pipeline. For instance, in Microsoft Word, the style will be upgraded to a block style, so a span that uses it inside a block will override the correct block style. It is best to define and use separate styles for blocks and spans.
