Interesting. Looks like the existing icon was already adaptive, so the actual changes are pretty straightforward.

Anyway, here’s my take on the design:

If type constraints later in the function let the compiler infer the type, this syntax totally works.

I’m no designer, but I’ll see if I can whip up something reasonable in Inkscape. I think I’ve got a handle on the process to turn an SVG image into an adaptive icon.
