Create scientific posters in Typst.

I recently came across a new typesetting system called typst. It is being developed by Martin Haug and Laurenz Mädje. It aims to modernize typesetting systems by introducing a new scripting language to control the layout of documents. There are many new and great things about typst and we could be talking about all of its aspects and compare it to $\LaTeX$ for quite some time. However, I would like to focus on how to actually use it and what this means in practice for someone that has used $\LaTeX$ since high-school.
