improove modularity of frenet site theme

I would like to reuse https://github.com/freenet/web/tree/main/hugo-site/themes/freenet .

but I can not do ` hugo mod init https://github.com/freenet/web/tree/main/hugo-site/themes/freenet` in a single line. Could we split the repo with a clonable theme with command ` hugo mod init https://github.com/freenet/web/` please?
