/**
 * The campaign in focus is the one the questions are about.
 *
 * Seen on dev on 23 Sep: starting on Meta and Google in one message put Meta in
 * focus, so choose_objective correctly offered Meta's five objectives, and the
 * panel beside it showed the Google campaign with Google's fields. The buyer
 * read "Needs a pixel" and "reactions, comments and shares" against a campaign
 * headed google.
 *
 * Neither half was wrong on its own. StartCampaign focuses the first platform
 * deliberately, with focus: $created === [], because the first is what the user
 * was talking about. Workspace::flush() then replayed every buffered artifact
 * through produced() without that flag, which defaults to true, so each one
 * re-focused as it was written and the last platform won.
 *
 * Only on the first message of a chat, because that is the only time artifacts
 * are buffered rather than written straight through.
