1. Ux idea: hover cards  
Description: if we hover over the card, then it is highlighted, but the element is not interactive (https://imgur.com/a/8Takm9i), BUT the "backers" button is interactive. I think you don't need to hihglighted card  on hover, but you need to indicate  the interactivity of the button.
