Answer 1

It turns out that there are a lot of outliners for sprites. The simplest one with UV shift and subtraction. Maybe someone will come in handy.

It will be easier to find an outlint asset for HDRP) It costs 9 bucks on the store, I can throw it off in principle. If you want to do it yourself, then maybe the Fresnel node will do.
