Wandmalfarbe/pandoc-latex-template ? reverse-engineered prompt

Build me a clean pandoc template for turning markdown into polished PDF and LaTeX documents, mainly for lecture notes, exercises, and technical writing.

I want it to look professional out of the box, with a nice title page, good headers and footers, readable code blocks, table of contents support, and sensible defaults for things like author, date, keywords, logos, background images, and page styling. It should also work well for a beamer slide version.

Please include a few example markdown files that show the template in action, plus a simple way to install or use it with pandoc so someone can generate a PDF from a markdown file quickly. If it makes sense, keep the template compatible with current pandoc versions and organize it so the main template can be used as a single file, but also have a multi file version under the hood if that helps maintenance.

If you need to check current pandoc or LaTeX docs online, go ahead.
