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

從受影響的教學頁面開始，使用螢幕截圖和 JSX 範例作為參考，在使用 Yarun-dark 主題的 Ubuntu 20.04 上透過 Chrome 重現大括號和小括號的呈現效果。追蹤頁面上顯示的程式碼樣式，並確認修復完成後，教學中的大括號和小括號在視覺上可以區分。
