Mobile-first QR Code Component

The header and paragraph are ever so slightly more prominent in the design than in my solution, despite the styling guide stating that it's supposed to be 15px. Nonetheless, I designed this QR code with mobile phones in mind first and noticed that the desktop version doesn't really require any media queries as far as I know.

Always open for feedback! Like my first challenge, would this be something worth animating when it appears front and center?
