MathFoundationRL/Book-Mathematical-Foundation-of-Reinforcement-Learning ? reverse-engineered prompt

Build me a clean homepage for the book Mathematical Foundations of Reinforcement Learning.

I want it to feel like an academic book landing page, with a short intro about the book, the author, and who it is for, then easy links to the table of contents, the full book PDF, the preface, each chapter PDF, the appendix, and the errata. Please also show the book cover, a simple visual of the chapter roadmap, and a section that highlights the lecture videos in a friendly way so students can start watching them easily.

Make it simple to read, polished, and responsive on desktop and mobile. If it helps, use the existing images and PDFs already in the project, and keep the design focused on the content rather than flashy. I’d also like a small citation block that people can copy, plus a note that the examples are based on a grid world task. If you need current best practices for a nice academic landing page, look them up online.
