Usage: sync-templates.ts [options]

Options:
  --all         Sync all templates (default behavior)
  --top-50      Sync top 50 templates by usage (shortcut for --limit 50)
  --limit N     Sync top N templates by usage
  --locale X    Sync only specific locale (e.g., --locale zh)
  --en-only     Sync English only (faster for development)
  --help, -h    Show this help message

Examples:
  pnpm run sync                  # Sync ALL templates (200+)
  pnpm run sync -- --top-50      # Sync top 50 by usage
  pnpm run sync -- --limit 100   # Sync top 100 by usage
  pnpm run sync -- --en-only     # Sync English only
