timlrx/tailwind-nextjs-starter-blog ? reverse-engineered prompt

Build me a polished personal blog site that feels like a modern technical writing starter. I want a clean homepage, a blog post listing page, individual article pages, and an easy way to write posts in Markdown or MDX so I can just drop content in and publish. Make it look good on mobile and desktop, keep the design minimal and fast, and use a nice Tailwind style throughout. Add the usual blog basics like tags or categories, an about page, and a simple way to update site info like the title, author, and social links without digging through a lot of code.

If you need to, look up the current Next.js and content setup docs online so it matches modern best practices. Please set it up so it is easy to customize later, since I may want to use it as a replacement for an old Jekyll or Hugo blog.
