/**
 * Prepares seed data by updating event dates relative to the current date.
 *
 * This script modifies items.json in-place, updating all items with
 * layer "layer-events" to have realistic start/end dates that ensure
 * events are visible in the app (end dates in the future).
 *
 * Date strategy:
 * - Event 1 (item-event-1): Long-running, started 30 days ago, ends in 365 days
 * - Event 2 (item-event-2): Upcoming single-day event in 7 days
 * - Event 3 (item-event-3): Ongoing event, started yesterday, ends tomorrow
 * - Event 4 (item-event-4): Upcoming multi-day conference in 30 days
