The complete native helper uses EDX as its byte-output address, original Stack0x18 as a source-byte lookup base and Stack0x1c as a byte blend-map base. Every remainder/chunk pixel reads a byte through both tables and writes one blended byte. Its only original caller forwards the unchanged destination, lookup and blend API values in those exact slots. Correct all three integer addresses and generic names coherently; preserve scalar clipping inputs, void return, fastcall, native arity and RET28. Table inputs are captured in EDI/ESI before their original stack slots are reused as scratch. The chosen Blend2AndClip name matches the verified operations.
