Coffee themed poster

A rich and inviting background for a coffee-themed poster featuring creamy coffee milk and golden caramel. Use dynamic splash effects of swirling milk, coffee, and caramel in mid-air, creating an artistic and energetic composition. The color palette should include warm browns, beige, and golden caramel tones. Add soft lighting and gentle gradients for a cozy and delicious atmosphere. No text, just a high-quality background suitable for a coffee shop poster.
