//! Public façade over `tempoch-core`.
//!
//! The crate root exposes the redesigned scale-only time model:
//!
//! - [`Time<S>`] for typed instants on a given scale
//! - [`Scale`] markers such as [`TT`], [`TAI`], [`UTC`], and [`UT1`]
//! - unified conversion targets via `time.to::<Target>()`, `try_to`, and
//!   `to_with`
//! - [`constats`] for epoch [`Time`] helpers plus [`qtty::Day`] / [`qtty::Second`]
//!   scratch constants
