I've started recently working on setting up the "special" public profile repository in GitHub to be my blog central and wanted to keep the files to a minimum. So, I really like using themes as modules in Hugo, then your blog repository will be just your content directory, go.mod, go.sum, hugo.toml, and any layouts you want to override or add.
