Responsive Card With QR Code With SASS

I usually develop the design part with a design created in Figma, often using a grid. When developing in React, I frequently use Emotion or Styled Components. This kind of challenge is interesting as it brings me back to the basics plus without Figma, but with a little extra touch – SCSS. I feel more organized and scalable with SCSS, even though this component may not be scalable (but it's still good practice, isn't it?).

I have a question about the title and the description – do h6 and p elements make sense, or would h4 be more appropriate?"
