The rendercv.renderer package contains the necessary classes and functions for
generating Typst, PDF, Markdown, HTML, and PNG files from the RenderCVDataModel
object.
The Typst and Markdown files are generated with
Jinja2 templates. Then, the Typst
file is rendered into a PDF and PNGs with
typst package. The Markdown file is rendered
into an HTML file with
markdown package.
