//! Core types, SQLite snapshot store, source traits, and velocity scoring
//! for trendkit.
//!
//! The crate is deliberately small: sources implement [`source::TrendSource`],
//! observations land in [`store::Store`], and [`score`] turns snapshot pairs
//! into per-day velocities. Time is always injected as a
//! [`clock_kit::Clock`] so collectors and scoring are deterministic under
//! test.
