Prompt tao anh chat luong cao. **Chi tiet cau lenh:** Create a premium ad for a fictional luxury chocolate brand called Velvet Bite. Make a realistic square product ad for one dark chocolate bar flavor. Keep the same core packaging system across each version: matte black wrapper, gold foil, elegant serif typography, premium product photography, and a high-end editorial feel. Create a different flavor world for each ad using the flavor name, colors, props, lighting, and mood. Flavor: Blood Orange Noir Dark chocolate, citrus, warm orange accents, dramatic shadows, gold foil, rich luxury feel. Flavor 2: Salted Pistachio Muse Dark chocolate, pistachio, soft cream background, green accents, elegant and refined. Flavor 3: Raspberry Ember Dark chocolate, raspberry, deep red backdrop, moody lighting, rich and indulgent. Each ad should include a bold headline, short supporting copy, the Velvet Bite chocolate bar as the hero product, flavor-specific ingredients around the product, and a small CTA that says “Shop the drop.” Make the ads feel realistic, premium, polished, and cohesive, like they all belong to the same brand campaign.
