A Call for Papers is not a paper. It is a hook, an outline, and a submit button — in that order.
This is part 1 of a three-post series shipped with the theme so /series/ and the post sidebar have something to render.
One sentence
If the reviewer cannot quote the talk in one sentence, they will not champion it. Write that sentence before the abstract, the title, and the demo.
What this site does with series
Set series: in front matter. The overlay lists the other parts in the right-hand column (under the article on small screens) and links the series name to /series/<term>/.
