"""
Integra órdenes puntuales de una tienda, de inicio a fin (Invoice -> Payment
-> ITR -> StockTransfer -> Delivery), sin pasar por el ciclo del scheduler.

Por defecto es DRY-RUN: valida cada orden y muestra el payload de la Invoice
y del Payment (este último armado sobre un total equivalente) sin escribir en
SAP ni en la base de datos. Con --apply inserta la orden en `orders` y corre
el pipeline real para ese id (crea documentos en SAP).

Uso:
  python -m tools.integrar_ordenes <store_code> <shopify_order_id> [...]          # dry-run
  python -m tools.integrar_ordenes <store_code> <shopify_order_id> [...] --apply
