1//! Module: subnet_catalog::json
2//!
3//! Responsibility: decode, validate, and encode subnet catalog JSON payloads.
4//!
5//! Does not own: cache paths, catalog fetching, or human text rendering.
6//!
7//! Boundary: keeps wire/file JSON conversion centralized so callers work with
8//! validated domain structs.
