//! Module: subnet_catalog::time
//!
//! Responsibility: derive catalog staleness metadata from canonical timestamps.
//!
//! Does not own: timestamp codecs, cache refresh policy, host IO, or report rendering.
//!
//! Boundary: Host owns UTC parsing; callers supply the observation time and age limit.
