Description

The card link chevron does not align with the divider line.

This is the original design spec in Figma (not aligned):

we use a simple chevron with no background, but the basic card in the NHS design system has a blue background circle

i suspect using the blue background circle would be far too heavy for the amount of them that we’d have, but if we sort-of-invert them, with a light grey circle BG and a blue chevron, we’d add a bit of visual detailing and be kind of close to the main NHS DS?

I think it's worth noting that the chevron is aligned 'correctly' when including its bounding box.
