Create a 9:16 vertical product advertising image for a debranded chocolate wafer snack called "Cocoa Crisp." Build the layout as a premium 2x2 gallery poster with four rounded rectangular panels arranged in a clean grid, unified by consistent margins, typography, and warm cocoa-brown brand color. Use the reference-image idea only for scene logic and visual hierarchy: dramatic floating wafer sticks, swirling liquid chocolate, suspended nut crumbs, glossy confection surfaces, and a high-impact central product presentation. Do not recreate any original brand marks, letters, packaging graphics, or protected text from the reference. Panel 1: hero composition with multiple chocolate-coated wafer rolls crossing diagonally in the center, crisp wafer interiors visible on one or two open ends, splashes of liquid chocolate wrapping around the product, scattered hazelnut crumbs, shallow depth of field, rich warm brown background with amber highlights. Panel 2: a clean packshot-style product focus showing one or two wafer sticks with controlled crumbs and a small copy area. Panel 3: an ingredient detail scene with chocolate coating texture, wafer layers, and nut pieces, presented as macro food photography. Panel 4: a lifestyle retail poster variation using the same product language, with a simplified chocolate swirl backdrop and clear headline placement. Materials must look physically believable: glossy melted chocolate, lightly rough nut-studded coating, crisp layered wafer interior, soft powdery crumbs, subtle condensation-free studio finish. Lighting must be controlled commercial studio lighting: key light from upper left, warm rim light from rear right, soft front fill to preserve packaging and food detail, bright specular highlights on chocolate, deep but readable shadows, cinematic contrast without losing texture. Typography must be minimal and production-ready. Use the exact headline text "Cocoa Crisp" in a bold modern sans-serif, placed clearly in one or two panels only, with strong legibility and generous spacing. Add small generic subheading and CTA placeholders such as "signature wafer snack" and "discover more" in lowercase or title case, but do not add prices, dates, addresses, phone numbers, certifications, or health claims. Keep text areas aligned to panel edges and leave at least one clean copy zone. Color palette: deep cocoa brown, milk chocolate, caramel amber, toasted hazelnut beige, and subtle cream highlights. Backgrounds should vary slightly across the four panels while staying within one coherent brand system. Emphasize premium snack advertising polish, sharp product edges, appetizing texture separation, clean retouching, and layered commercial poster finish. Negative constraints: no real brand logos, no embossed letters, no social handles, no celebrity likenesses, no prices, no discount badges, no barcode, no legal pack text, no extra hands, no messy composition, no melted product deformation, no unrealistic crumbs, no copied packaging design, no protected slogans. Reference-image policy: use the unseen reference only as inspiration for composition intensity, splash dynamics, lighting mood, material realism, and premium food-ad finish; generate a new original layout and new brand-neutral design.
