Ocyan Mollie provider core
==========================

``ocyan.mollie`` provides the low-level Mollie boundary used by MandelBlog
payment adapters. It creates the official Mollie SDK client only at runtime,
validates amount/currency payloads, and provides classic-webhook primitives.

It does not read credentials at import time. Applications must supply
``MOLLIE_API_KEY`` or their approved runtime setting only when a payment
operation is requested. Never commit provider credentials.

The legacy ``MolliePaymentMixin`` remains available for backwards
compatibility with existing Oscar integrations. New checkout work belongs in
an adapter such as ``ocyan.plugin.payment_mollie``.
