Fading the whole preview to a black overlay for the loading state was feeling aggressive, especially since loading delay wasn't working correctly!
In this change, I fix loading delay, and I add a nice subtle "corner" variant for outfit preview spinners :)
Here, we add loading skeletons to lots of individual elements, instead of doing a whole item placeholder skeleton. That helps when coming from pages where we have some data, like name and thumbnail, but things is isNc are still missing.
It looks nice, but also particularly means we can handle the loading for the preview separately, get that started faster and iterate better on it in dev!
