How do I integrate BLIK in Magento 2?

BLIK is the Polish mobile-pay standard, ~24M+ active users, the most-used payment method on Polish e-commerce after card. The flow:

1. Customer picks BLIK at checkout.
2. Opens their banking app (PKO BP, mBank, ING, Santander, Millennium, etc.) and taps “BLIK code”.
3. App shows a one-time 6-digit code (valid ~2 minutes).
4. Customer types the code into Magento checkout.
5. Bank confirms in the app, transaction settles in seconds.

BLIK is operated by Polski Standard Płatności (PSP). In Magento you don’t integrate BLIK directly, you integrate via a PSP that supports it:

• Przelewy24 (P24), most common route, BLIK enabled by default. Free Magento module.
• PayU Poland, BLIK enabled, official Magento 2 module from PayU.
• Tpay, BLIK + bank-transfer + cards, Polish PSP.
• Stripe Poland, BLIK supported via stripe.js, cross-border friendly.
• Blue Media / Autopay, BLIK + fast-bank-transfer, popular with PL retailers.

Without BLIK, ~40% of younger Polish shoppers (18-34) bounce at checkout because card-typing feels obsolete.
