//! The position-aware scope *shape* tests migrated to
//! `nibli-kr/src/shape_tests/scoping.rs`. What stays here is the one case with
//! no KR surface: a `da` in a `WithArgs` (be/linked-args) with a universal —
//! the be-arg has no proposition-level surface position, so it is closed
//! innermost, and `WithArgs` at bridi level is only hand-buildable.
