/**
 * Phase 3 mobile — long-press gesture.
 *
 * The `longpress` action attaches to `<article>` in FeedListCard and to
 * grid cells in VirtualFeed (grid mode). Holding for ≥ 500 ms fires `onlongpress`,
 * which opens the ContextSheet bottom sheet via the feed page's
 * `contextTarget` state.
 *
 * Setup needs at least one upload to render a card. We post via the
 * Phase 2 upload-client helper, then drive the gesture with the touch
 * helper.
