Sorry, submitted the issue a bit too early. A few other changes: -instead of the blue button, can we use the link text similar to the ecosystem page -can be make the spacing and the rounded corners of the cards the same as the ecosystem -the title of the cards can also be a bit smaller, similar to the ecosystem card titles
