Build me a website that lets someone keep writing in Notion and publish it as a fast, polished site. It should work for a personal blog, portfolio, knowledge base, product landing page, or simple docs site, and let me switch between a few different looks without changing the content in Notion. I want the site to pull pages, posts, tags, categories, and menus from Notion, then render them nicely with good SEO, search, sitemap, RSS, and optional comments or analytics.

Make it easy to set up with a simple config and environment variables, and make sure it can be deployed without needing my own server. A clean homepage, article pages, navigation, and a theme system are the most important parts. If you need to check current docs for deployment or API details, look them up online.
