tpn/pdfs ? reverse-engineered prompt

Build me a clean little website for browsing a big collection of technical PDFs and related docs.

I want people to be able to search by title, quickly scan through the library, and open files from a simple catalog style page. It should feel fast and easy to use, with some way to narrow things down when there are lots of similar papers, manuals, slides, and specs. The home page should make the collection feel organized, not overwhelming, and it should work well on desktop and mobile.

Keep it focused on the documents in this repository, and make it easy to add more files later without redoing the whole site. If you need to look up current docs or best practices for static site behavior, go ahead and check online.
