Facia cards half design tweaks

A series of mergeable design fixes from [`facia-cards-design-tweaks`](https://github.com/guardian/frontend/tree/facia-cards-design-tweaks), as to not conflict with @sndrs work with sublinks.

[`facia-cards-design-tweaks`](https://github.com/guardian/frontend/tree/facia-cards-design-tweaks) will be manually rolled into his branch when it's ready.
