Asabeneh/30-Days-Of-React ? reverse-engineered prompt

Build me a simple learning website for the 30 Days of React challenge.

I want it to feel like a friendly course hub where someone can browse all 30 days, open each lesson, and move through the topics in order from JavaScript refreshers to hooks, context, refs, and the final conclusions. Make the homepage explain what the challenge is, and make the day list easy to scan and click into. Each lesson page should be clean and readable, with headings, code examples, and space for notes or exercises.

Please keep the design lightweight and beginner friendly, since this is for people who are just learning React. If you need any current docs or best practices, look them up online.
