QR Code Component

The project looks great. Here are a couple of my feedback:

1. CSS Naming Convention: I see you're using class names like text-preset-1 and text-preset-2. While it's functional, using more descriptive names (like .main-heading or .subtext) could make the code more readable and easier to maintain, especially as the project grows.

2. Unused CSS: I noticed that .text-preset-2 is defined in the stylesheet but isn't applied to any element in the HTML.
