1//! # Thin JSON (de)serialisation helpers
2//!
3//! Four trivial wrappers over `serde_json` that return `anyhow::Result` and either
4//! `Bytes` or `String`. The point is consistency: every caller in the codebase goes
5//! through these helpers instead of sprinkling `serde_json::to_vec` / `from_slice`
6//! calls, so error handling and encoding choices stay uniform.
7//!
8//! JSON is used for the rare human-readable persisted blobs (configuration, on-disk
9//! key locker entries). Wire-format payloads go through the hand-rolled binary
10//! encoders in [`crate::protocol`] instead.
