Remove unused card styles

There are no links inside a figure-card, so these styles didn't affect
any elements.

There are also no elements with `.title`, and the h3 inherits the white
color automatically form the figcaption.

On the other hand, the .see-all link is not inside an element with a
`card` class since commit fae52274a.
