//! White-box unit tests for the canonical writer's private helpers.
//!
//! Only the tests that exercise a NON-public writer primitive remain here; they
//! cannot move to `tests/` because they reach into `super::` internals. The
//! round-trip / public-API suite lives in `zenith-core/tests/format_writer*`.
