There is actually a small watermark in the corner of some cards (just to spread the word a little bit), but it's so small and transparent that you can't really notice it unless you zoom in and look really closely.
But it can be removed by copying `localStorage["please-dont-remove-the-watermark"]=true;` into the browser console, or by using a design you made yourself.
That's a good idea about printing it out - I'll look into it!
