• Ensure that every design decision made is clearly aligned with and contributes to specific commercial objectives and KPIs.

📝 Enhancement Note: The responsibilities highlight a strong bias towards measurable business outcomes (conversion, commercial performance) rather than just aesthetic appeal.
