Should item pin number inherit from the icon styles?

Subject of the enhancement

With the current implementation (PR #281), the visited state pin displays larger than the unvisited number. The visited state inherits from @icon-size (1.5rem) whereas the number pin inherits from @body-size (1rem).

Should .hotgraphic__pin-number inherit the icon styles instead for consistency of item size? See screenshot below.

we could update the .hotgraphic__pin-number to inherit the icon styles instead.

@kirsty-hames I prefer this option so that the pin circles don't change sizes once visited. I don't have a preference about inheriting from the icon styles or something else, as long as the pin circles don't change sizes.
