//! - `zeroize` — secure memory zeroing
//! - `subtle` — constant-time comparison primitives
//! - `hex` — hexadecimal encoding/decoding
//! - `getrandom` — OS entropy extraction
//! - `rand_chacha` — native ChaCha20 CSPRNG
//! - `sha3` — SHA3-256/512 hashing
//! - `hmac` — HMAC-SHA3-256
//! - `hkdf` — HKDF-SHA3-256 key derivation
