//! `cfg(mf2_workspace)`: this crate is being built in its repository, not
//! from its package. The unit tests that read the repository around the
//! crate (`src/workspace_tests.rs`, `src/convert/leptos_fluent/tests.rs`)
//! are left out of the package, and compile only where they are
//! (`plans/17-phase-9-work-order.md` A4).
