/**
 * Seeds the top-level `date_ideas` collection from date_ideas_seed.json.
 *
 * A LOCAL admin script — NOT a deployed callable (a deployed admin-write endpoint is avoidable
 * attack surface). Run with admin credentials; idempotent by document id, so re-running updates in
 * place rather than duplicating. Sponsored/seasonal ideas are edited here and pushed without an app
 * release; the Android app falls back to its shipped static seed when the collection is empty.
 *
 * Usage:
 *   export GOOGLE_APPLICATION_CREDENTIALS=~/.config/closer/closer-admin-sa.json
 *   npx ts-node functions/scripts/seedDateIdeas.ts            # writes
 *   npx ts-node functions/scripts/seedDateIdeas.ts --dry-run  # prints what would change
