//! Write the "email you cannot turn off" guide page from `email::OperationalKind`.
//!
//! The docs tree is static markdown, so the page is a checked-in artifact rather
//! than something rendered per request. `email::class::tests::
//! committed_doc_matches_generated` fails when this output is stale, so the
//! regeneration step is:
//!
//! ```sh
//! cargo run --bin export-operational-mail-doc
//! ```
