Tutorial font hard to read

I worked through the tutorial today, it suggests:

We strongly recommend typing code by hand as you’re working through the tutorial and not using copy/paste. This will help you develop muscle memory and a stronger understanding.

I agree with it, but I found impossible because I cannot tell the difference between Braces {} and Parentheses () due to the font.

I'm using Chrome on Ubuntu 20,04 with the Yarun-dark theme so perhaps that causes the issue.

For example the left braces in the copied image below look like parentheses

rather than

  renderSquare(i) {
    return <Square value={i} />;
  }

The right braces on below look different on the value= and onClick= lines as well

Comece pela página do tutorial afetada e reproduza a renderização de chaves e parênteses no Chrome no Ubuntu 20.04 com o tema Yarun-dark, usando as capturas de tela e os exemplos de JSX como referência. Rastreie o estilo do código exibido na página e verifique se as chaves e os parênteses são visualmente distinguíveis no tutorial quando o fix for concluído.
