//! Snapshot tests — powered by `insta`.

//! These tests capture the exact output of pure functions and stable

//! review` shows a diff for human approval.  This catches accidental
//! regressions in security-critical classifiers and provider metadata.

//! Run: `cargo test -p koda-core --features test-support --test snapshot_test`
//! Review: `cargo insta review`
