home-assistant/home-assistant.io ? reverse-engineered prompt

Build me a clean documentation website for Home Assistant that matches the style of the current Home Assistant site. It should be a static site people can read easily, with pages for guides, help articles, and release notes, and it should support local preview while I edit so I can see changes at http://127.0.0.1:4000.

I want it set up so I can run it locally, make content changes, and preview the result quickly. If there are long release note pages slowing things down, make it easy to temporarily leave those out and bring them back when I am done. Please make sure the site is ready for normal docs work, with a simple way to serve it, and keep the structure friendly for contributors. If you need to check current docs for the best way to run or build it, look that up online.
