## What Changed

Google Pay integrations on KOMOJU Hosted Page and Hosted Fields now apply the merchant's card brand configuration and route payments through full 3D Secure challenges. The Google Pay sheet only displays cards from networks enabled on the merchant's account.

## Merchant Impact

Customers can no longer select a card brand the merchant does not accept. This prevents checkout errors caused by unsupported card brands.
