//! Bank Indonesia SNAP BI recipe helpers.
//!
//! Everything in this module is *spec-prescribed plumbing*: stringToSign
//! canonical formats, SHA-256 lowercase-hex body hashing, ISO-8601 Jakarta
//! timestamps, and canonical header sets. Centralising the recipe here means
//! every PT IMMER consumer can avoid reinventing the colon-separator,
//! lowercase-hex, or timezone offset rules — each of which has historically
//! produced opaque `4011100` failures in production.
//!
//! Feature-gated behind `snap-bi` (default on). Pulls `chrono` (timestamps) and
//! `http` (Method / HeaderMap types).
