2D outline shader - looking for advice

[winged sigil]

Hi, I'm trying to implement a clean outline with high resolution with a shader. I tested different paths, but the quality is always worse than "outlines directly included in the PNG from my Affinity Designer vector sprite".
Any advice?

For sprites id recommend doing a shader that does edge detection to produce an outline
you may need to adjust the sprites however to provide enough space to draw the outline however (otherwise it will need some extra steps in shader to down size the sprite to make space)
