Constants

MAX_ADDRESS_INPUT_BYTES

Maximum byte length accepted by the address-list parser before rejecting outright. 64 KiB is far above any realistic header value , RFC 5322 caps physical lines at 998 bytes; even a header folded across hundreds of continuation lines stays well under this. The cap exists to prevent the format!("To: {input}\r\n\r\n") allocation amplification on adversarial multi-megabyte input.
