/**
 * Imports content fixtures from `content/**` into the Payload database so
 * editors can find and modify them in Admin.
 *
 * The CMS is the editor's source of truth at edit time; the Git repo is
 * source of truth at runtime. This script bridges the two on demand: run it
 * after a fresh DB boot or after a content PR merges, so the Admin view
 * reflects the latest committed state.
 *
 * Plan §Phase 3 envisions an automatic `beforeRead` hook to do the same
 * job inside Payload itself — this script is the manual interim until that
 * lands.
 *
 * Usage:
 *   cd apps/cms && set -a && source .env && set +a && \
 *     pnpm sync-from-content
 *
 * Skipped (out of scope for this script):
 *   - Press articles: fetched directly from Logos Press Engine
