Oh no, how utterly annoying! Peeling off masks is such a tense process. I'm willing to bet on you recovering this though.
Best of luck

I sprayed the primer, then each of the other colours one at a time. So in theory, they are all roughly the same thickness
This means there should be a raised bit along the edge of the white to paint up to. So, I'm hoping to repair the damage by hand with a brush
