// The labels each component takes, built from a message lookup. Every key this module's pages use is
// named here and nowhere else, so `__tests__/i18n.test.ts` can run these builders against the
// catalogues and fail on a key either language lacks -- the page itself holds no string.
//
// `t` takes a key relative to the module (`form.create`); the page binds it to
// `i18n.message("notes." + key)`. The one message that is not this module's own, the app's
// `app.failed`, is passed in already looked up.
