title: js and css not loading when hosting next application on GitHub pages
body: <p>Next.js builds all the static assets in <em>_next</em> folder but Github pages does not need to serve those files. I am 404 for static assets.</p>
  
  <p>Example repo: <a href="https://github.com/ajaymathur/ajaymathur.github.io" rel="noreferrer">https://github.com/ajaymathur/ajaymathur.github.io</a>
  Master branch is hosted and dev branch is for development.</p>
  
  <p>And I guess github pages is not hosting paths starting with <strong>-</strong>. How can I get around this issue?</p>
