@timothyylim not sure if this should go in or #1312

[carsonfarmer]

They are almost identical, so probably doesn't matter. I'll stop picking these up so I don't trample your PRs! Having said that I personally like this one because it keeps the white border, but it's @stephhuynh18's call!

[stephhuynh18]

i'll defer to @jovirecall #1312 or this one? You discussed this one with @carsonfarmer butttt you also approved @timothyylim's in the linear ticket.

Meh, just use the other one, it looks great!
