//! The GM help window (decision 1673, HelpFrame.xml): the category list the DBC feeds it, the two
//! faces of `UPDATE_TICKET`, the queue gate, the ticket toast, and the three dialogs.
//!
//! Written as the **falsification** pass over the transcription rather than a demonstration of it:
//! every test is named after one claim the window makes, and each was checked to fail when the
//! claim is broken. The load-bearing one is
//! [`clicking_a_category_files_a_ticket_under_that_categorys_dbc_id`] — the id travels from
//! `GMTicketCategory.dbc` through a button, a page, and the editor onto the wire, and a break
//! anywhere in that chain files every ticket under the wrong heading with nothing on screen to
//! show for it.
