#![expect(clippy::panic, reason = "test scaffolding")]
//! Guard that `website/docs/changelog.md` stays in sync with `CHANGELOG.md` (#258).
//!
//! `website/docs/changelog.md` is a generated artifact derived from the root
//! `CHANGELOG.md`. The derivation is handled by `scripts/sync-changelog-doc.sh`.
//! This test replicates the transformation and asserts the committed file matches,
//! so a PR that edits `CHANGELOG.md` without re-running the sync script fails CI.
