//! Help-footer guard: `ms --help` points lost-passphrase users at btcrecover.
//!
//! Mirror of the `mnemonic` CLI footer (recon decision 2026-05-25): a BIP-39
//! passphrase has no internal verifier, so `ms` cannot brute-force it from the
//! entropy alone — that is an external-derivation-oracle attack, which
//! btcrecover performs. Assert the load-bearing substrings only (name +
//! maintained repo + date stamp); exact rendering is clap-version-sensitive.
