Smart carton/packing logic and shipping-cost adjustments for WooCommerce.

== Description ==
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.

== Installation ==
1. In WordPress admin, go to Plugins -> Add New -> Upload Plugin.

Yes. WooCommerce must be active.
