buffer = bytearray(64 * Size.KB)  # a buffer of 64 kibibytes, rather than a bare 65536
say_size4(123456789)  # "117 MB": four digits or less, with a unit
deadline = now + 2 * Time.HOUR  # two hours after a tick, in milliseconds
tick_to_text(deadline)  # "2026oct15.2041.7125", a tick's short exact text
tick_to_iso(deadline)  # "2026-10-15T20:41:07.125Z", the same tick's iso text
d = Data(text="hello")  # bytes, out as base16, base32, base62, base64, or text
sha256(d).base32()  # the SHA-256 hash, as a Data; sha1 and blake3 the same
