//! Scepter provides composable primitives for large-scale time-series systems:
//! schema-rich keys, lexicographic routing, approximate field-hint indexing,
//! mergeable distributions, ingestion aggregation, and distributed query
//! planning.
//!
//! The crate is inspired by the public Monarch paper, but it is an independent
//! Rust library design intended for observability systems, log search, stream
//! processing, and distributed query engines.
