//! The top-level `router()` entrypoint (cratestack#328). Under
//! `db = Postgres` it merges `model_router` + `procedure_router` as
//! before. Under `db = None` there is no `model_router` at all (see
//! `super::model_router`'s module doc), so `router()` is simply an alias
//! for `procedure_router` — schema-author bootstrap code calls the same
//! `router(db, registry, codec, auth_provider)` entrypoint regardless of
//! `db` mode, it just merges nothing under `db = None`.
