gohugoio/hugo ? reverse-engineered prompt

Build me a really fast static site generator in Go that people can use to make blogs, documentation sites, landing pages, portfolios, and resumes from simple content files and templates. I want it to render a full site in seconds, include a built in local web server with live reload while editing, and be flexible enough to handle reusable themes, menus, tags and categories, related content, and multilingual sites.

It should also have a solid asset pipeline so stylesheets, Sass, JavaScript, TypeScript, JSX, and images can be bundled, transformed, optimized, and fingerprinted for production. Make image handling useful too, with resizing, cropping, filters, overlays, and metadata when possible. The output should be plain static files that are easy to host anywhere.

Please make it feel polished as a command line tool, with sensible defaults, clear docs, and a straightforward way to build from source. If there are optional features like direct cloud deployment or extra Sass support, include them in a clean way. Look up current docs online if you need to.
