<context>
This is a triage decision ticket. It must be resolved before dependent implementation tickets can proceed.
</context>

<question>
4-word passphrase crate selection: which crate generates 4-word passphrases and compiles for wasm32-unknown-unknown without std thread-local RNG or filesystem access?
</question>

<options>
1. **passphrase-wordlist** — small crate, check WASM compatibility.
2. **bip39** — BIP-39 mnemonic words, widely available. Returns 12-word phrases by default; can take first 4 words.
3. **Custom word list** — embed a static word list in `src/lib.rs` and select 4 random words using `getrandom` with the `js` feature for WASM-compatible randomness.
</options>

<resolution>
1. Research the options above and choose the best approach for this project.
2. Update ticket 03bb91 (auth_code generator) and `Cargo.toml` (ticket 1f5bb5) with the chosen crate.
3. Mark this ticket done with a note on the chosen approach in the body or a comment.
</resolution>
