//! Offline integration smoke test for the layer-2 differential pipeline
//! (`docs/TESTING.md` layer 2). It runs real wikitext through the same path
//! `xtask diff-report` uses — `parser::parse` -> `render::plain` ->
//! `diff::classify` — against hand-written ground-truth prose, so CI verifies the
//! end-to-end bucketing WITHOUT network. The full N-page run is
//! `cargo xtask diff-report` (manual / scheduled, per TESTING.md).

/// anything `Unsupported`.
