Hey there 👋
I noticed the background for the iDeal page, and in some other places, is just a background image. On a high-resolution display, this can look a bit unsharp.
I knew there must be a better way, so I took the liberty to make a pure CSS variant. This way it's always 100% sharp.

I hope it can be useful 👍
