🌸 DESCRIPTION 🌸

WARNING: no matter what your system locale is doing, this will only convert ASCII values 'A' through 'Z' to lowercase. That's it. That's the whole conversion. 💀

This function operates on a null-terminated string of bytes — even if it is malformed UTF-8! — and converts ASCII characters 'A' through 'Z' to their lowercase equivalents in-place, returning the original str pointer. Periodt. 💅

like, it does not care about your encoding drama, it does not allocate, it just reaches in and lowercases the ASCII letters right where they live. iconic behavior honestly ✨
