LowerASCII :: (value: u8) -> u8StartsWithFoldASCII :: (value: string, prefix: string) -> boolContainsFoldASCII :: (value: string, needle: string) -> boolModules / Standard library
ASCII-only case folding keeps the result identical across native targets and the portable runner. UTF-8 bytes outside ASCII compare unchanged.
