Copeaux de beurre sur toast : affiche luxueuse produits laitiers

Create a premium vertical food advertising poster for a fictional dairy brand called LUNERA, refined in a more international and flagship Transit direction. Preserve the core visual logic exactly: a strong vertical split background with a saturated crimson-red field on the left and a smooth light walnut-brown tabletop field on the right, viewed from a clean top-down to slightly angled flat-lay perspective. One hero slice of toast with sculpted butter curls and one premium wrapped butter package must remain the central commercial story, supported by a silver butter knife, a few butter cubes, and a few restrained nut fragments. The whole poster must feel cleaner, more editorial, more globally premium, and more controlled than a standard FMCG layout. Main product story: Place one slice of golden toast near the center-right area, topped with several elegant curled ribbons of pale creamy salted butter. The butter curls must be the main appetite trigger: smooth, sculptural, softly luminous, with believable thickness, creamy density, and refined highlight rolloff. Near the toast, position one premium wrapped butter package in the lower-right area, angled slightly, with a clean original fictional label design in cream and red, highly legible but understated. On the left side, place a silver butter knife entering inward with a soft dollop of butter on the blade, creating a subtle diagonal relation toward the toast. Scatter only a very small number of butter cubes and nut fragments to keep the composition airy and premium. Food realism: Render the butter with exceptional realism and restraint: pale warm yellow tone, softly spreadable texture, crisp cut edges, satin creaminess, gentle sheen, and beautiful curl structure. The toast must show delicate porous crumb, crisp browned edges, and refined bakery realism without over-texturing. The wrapped butter block should feel substantial and premium, with believable wrap folds, precise shadowing, and elegant print finish. Small butter cubes should feel fresh, slightly softened, and neatly composed. Typography and branding: Use a fully original premium typography system. Place a small brand mark and short supporting line near the upper-left or upper-center. Add one bold English headline block on the left red field, using original copy such as “SLOW CRAFT. PURE INDULGENCE.” or “LAYERED SOFTNESS. DAILY LUXURY.” Add one compact supporting line near the lower-left and one small brand statement near the upper-right area. All copy must be original, sparse, and highly controlled. Typography should feel more editorial and luxurious than promotional, with cleaner spacing and stronger hierarchy. Lighting and mood: Use soft directional premium studio lighting from upper-right, giving the butter curls delicate highlights, the knife subtle metallic gleam, the package soft dimensionality, and the red and wood surfaces elegant tonal transitions. Increase realism and material separation, but keep the shadows clean, soft, and international in feel. The whole poster should feel polished, appetite-rich, and confidently premium. Style: International flagship dairy campaign, premium FMCG food branding, editorial commercial poster, hyper-real food photography, minimal prop styling, luxury supermarket launch visual, Cannes-level product hierarchy. Everything should feel more distilled and globally premium than a local retail ad. Color system: Deep crimson red, warm walnut brown, creamy pale butter yellow, golden toast beige, silver knife, restrained cream-and-red packaging accents. Keep the palette minimal, bold, elegant, and highly memorable. Negative prompt: no copied brand names, no copied slogan, no cluttered props, no messy crumbs everywhere, no melted butter chaos, no low-detail toast texture, no warped package, no muddy shadows, no black blotches, no dirty tabletop, no cheap supermarket mockup look, no watermark, no existing logos.
