I'm doing this in preparation for an API endpoint to build outfit images by ID. It'll need the same logic to decide which layers are visible, and the same GQL fragments to load the relevant data!
To help the load time for outfits feel shorter, we now reuse the outfit thumbnail from the Your Outfits page as a placeholder!
This doesn't add any overhead when the thumbnail data _isn't_ in your session cache, e.g. if you navigate to the outfit directly. But if we have the thumbnail on hand already, we just show it, easy peasy!
