//
// On Linux, FreeBSD, Dragonfly, NetBSD and Solaris, Reader uses getrandom(2) if
// available, /dev/urandom otherwise.
// On OpenBSD and macOS, Reader uses getentropy(2).
// On other Unix-like systems, Reader reads from /dev/urandom.
// On Windows systems, Reader uses the ProcessPrng API.
// On JS/Wasm, Reader uses the Web Crypto API.
// On WASIP1/Wasm, Reader uses random_get from wasi_snapshot_preview1.
