//! Unit tests for the `app` module.
//!
//! One module per surface, mirroring the `app/` submodule split. The
//! bodies moved verbatim out of a single 9,515-line file; `use
//! super::super::*` in each resolves to `crate::app`, exactly what the
//! flat file's `use super::*` gave them, so every test still sees what
//! it did when it lived inline.
//!
//! Shared fixtures live in `support` and are `pub(super)`, which makes
//! them visible to every sibling here.
