[Feature] Add Portuguese (Brazil) Translation & Improve Website Layout

[leonardopinezi]

Hello! 👋

First of all, congratulations on the project — it's very helpful and well-organized!

I'd like to suggest two improvements:

1. Add a Portuguese (Brazil) translation (pt-BR):
   This could help Portuguese-speaking users (from Brazil and Portugal) understand the content better, especially beginners learning JavaScript.

2. Improve the main website layout:
   A slightly more polished and modern layout could make the site even more attractive and user-friendly.

I'd be happy to help with the translation or layout suggestions if you're open to contributions.

Thanks, and keep up the great work! 🚀

@leonardopinezi Thank you for the feedback. A Portuguese translation would be wonderful. Given the scope of work involved, I recommend an incremental release approach.
