felipefialho/frontend-challenges ? reverse-engineered prompt

Build me a simple public website that lists front end job challenges from companies around the world. It should let people browse the challenges in a clean table or directory, see the company name, country or language, stack, and a link to the challenge repo, plus a link to jobs when there is one. I want it to feel easy to scan and compare, with search and basic filters so someone can quickly find challenges by company, tech stack, or language.

Keep the design straightforward and polished, with a nice landing page that explains what the site is for and makes it clear these are open source practice challenges. Add a responsive layout so it works well on mobile too. If you need to check current docs or best practices for anything, look them up online.
