scrimba/learn-fullstack-development ? reverse-engineered prompt

Build me a simple course site for a full stack developer learning path, with sections that match the lessons in the repo, from the introduction all the way through React, TypeScript, Next.js, and launching your career.

I want it to feel like a friendly study companion, so someone can open a topic, see what they are learning, and move through the course in order. Keep the design clean, easy to read, and responsive on phones and desktop. Make the navigation obvious, with one place to jump between sections and clear labels for each chapter.

If anything from the course needs current best practices, look up the latest docs online and use those. Focus on making it polished, beginner friendly, and useful for someone following along with the tutorial videos.
