Carton Optimizer for WooCommerce

Carton Optimizer helps you estimate how many cartons an order needs and optionally adjust shipping rates based on your rules.

Main features:
* Product “carton points” field to estimate space/volume
* Max points per carton and optional buffer points (auto/always/off)
* Per-shipping-method surcharge (for example: extra fee per additional carton)
* Admin UI language switch (EN/PL)

Works on WooCommerce cart/checkout by filtering available shipping rates.
