This week you start your real app in **Flask** so you own every line of code. Your v0 prototype (React/Next.js) is a great reference: https://v0.app/chat/movie-and-album-ratings-gHlvwCzKPL5?ref=WBY3CM **Important:** v0 can look very polished.

Each returns HTML as a string. Use Tailwind classes instead of giant `
