/**
 * A FLOW THAT BELONGS TO AN ORGAN SAYS SO.
 *
 * Herald's reply flow is stored where the owner's own automations are, so it already appeared on the
 * Automation tab — as an anonymous card that looked hand-drawn, whose trigger read "manual" (nobody
 * presses it; Herald does), and which offered a Delete that would have silently stopped every reply
 * the desk sends, with nothing on screen to say what broke.
 *
 * `owner` is who shipped it. Editing stays open on purpose — the owner may want to see or tune what
 * her desk runs, and the organ reconciles by name on its next restart.
