Luxury chocolate campaign system

Create a premium, square (1:1) product advertisement for a fictional luxury chocolate brand called Noirvelle Chocolat, inspired by high-end chocolate brands. The ad should feel like a high-end editorial campaign, combining luxury food photography, refined packaging design, and cinematic lighting. Use matte black wrapper, subtle gold foil, elegant serif typography, and realistic product rendering. Generate flavor variants such as Blood Orange Noir, Salted Pistachio Muse, and Raspberry Ember with distinct mood, color palette, ingredients, headline, and supporting copy. Keep the chocolate bar as hero centerpiece with subtle reflections, shallow depth of field, luxury minimalism, and a small CTA: "Shop the drop."
