@bitwarden/dept-design Can you verify that the padding between options here looks correct? There's a couple different examples in figma so I wanted to find a decent standard.

(also feel free to check out the Chromatic as well)

@jlf0dev Can we do no margin between the hint and radio button? Then between each hint/radio button group can we do .5rem of margin?

After a quick design review, we need to make some bigger layout changes to the radio component. Converting to a draft for now.
