## As this is just for API > 33, we don't need to export to png mipmaps, we can just directly use the drawable
# note that the monochrome svgs are also in this directory and could be directly converted to png mipmaps in the same
# way as ic_launcher_foreground_sc.svg above, but we're sticking with manually imported svg -> xml drawables
# for now to ensure high fidelity and sidestep issues with reproducibility of icon generation
