// Row 54 (#1543): the Queue, Business and Settings views in a browser. Each view in its five
// states over a stub read: loading, normal, empty, a failed read over kept data, and a refusal
// that shows nothing kept. Queue rows move only with `queue move`, so the page shows that command
// and no button for it. Over the seeded fixture (reads-fixture.mjs), no secret, Discord id or
// temporary path reaches a response, the page or the server's log, and a missing or invalid
// business file shows the business module's own refusal text. Nothing here writes.
