Do a slide-based presentation
Suppose you want to do a presentation that consists uniquely of slides. In this
case, you can add children:slide children:enter=~duration:0 as
toplevel-attributes in the frontmatter.
Once you have added this in the frontmatter, separate your slides with ---,
just like you would in a revealJS presentation. The rest of the syntax
({pause}, etc) and feature stay unchanged.
