Create a futuristic retail environment where a customer is being assisted by a life-sized holographic AI assistant. The store should be bright, minimalistic, and sleek, with white walls and modern decor, reflecting a clean and high-tech atmosphere. The holographic assistant should appear projected in front of the customer, providing personalized product recommendations and interacting with the customer in real-time. The hologram should have a futuristic yet approachable design, with glowing purple accents (matching the Clack branding), along with subtle steampunk elements like metallic details and gears subtly incorporated into the hologram's base or interface. The customer should be clearly visible, standing in front of the hologram, engaged with the assistant. The store shelves should display products in a minimalistic manner, with floating holographic labels and augmented reality interfaces showing additional product details. The scene should feel open, welcoming, and technologically advanced, with a focus on seamless human-AI interaction for an enhanced customer experience. Ensure that the environment is well-lit and clean, so it integrates smoothly with the white background of the Clack website, while maintaining a balance between futuristic and steampunk aesthetics
