vuejs/vuepress ? reverse-engineered prompt

Build me a simple Vue powered static site generator for docs and blog style websites, something I can point at a folder of Markdown files and get a clean website out the other end. I want it to support writing pages in Markdown, adding a site title and navigation, and letting me customize the look with Vue components when I need something more than plain text. It should be easy to run locally for editing, then build for production with good SEO friendly output and fast page loads.

Please make the docs site itself work too, with a homepage, sidebar navigation, code examples, and a nice default theme. If anything is unclear, look up the current docs online and follow the project’s existing style. Keep it lightweight and polished, and make sure the whole thing can be developed, tested, and built from the repo without a lot of extra setup.
