"""Makes the static Sora fonts shipped in resources/fonts from the variable font of the google/fonts repository.

stb_truetype (used by NanoVG) reads only a variable font's default instance, so each weight is instanced.
Usage (once, needs fontTools):
    curl -L -o Sora.ttf "https://github.com/google/fonts/raw/main/ofl/sora/Sora%5Bwght%5D.ttf"
    python3 scripts/make-sora.py Sora.ttf resources/fonts
