4-панельная сетка цифровых рекламных баннеров в японском стиле

Design a square 1:1 advertising gallery poster as a 2x2 grid of four equal banner panels with thin white gutters and consistent outer margins. Treat it as a debranded commercial showcase for multiple campaign categories, unified by one typography system, one badge system, and one color-management approach. Place the exact headline text "Launch Campaign" once as the master gallery title in a clean top overlay or as a shared campaign tag that does not overpower the panel headlines. Each quadrant must have its own distinct hero subject and atmosphere, but all four must feel like one professional ad set with aligned spacing, matching corner radii, consistent icon style, and clear reading hierarchy. Panel 1, top-left: a travel-themed banner with a bright tropical coastline, white sand, turquoise water, blue sky, and two anonymous adults seen from behind or in three-quarter back view to avoid identity specificity. Use a fresh aqua, sky blue, and sunlit yellow palette. Add a bold headline zone in the upper left, a secondary ribbon label, a large offer block area, and three small circular service icons near the lower area. Lighting: hard daylight with crisp highlights, clean atmospheric depth, and vivid yet controlled saturation. Materials: glossy water, soft fabric, palm leaves, subtle print-poster finish. Panel 2, top-right: a skincare-themed banner with a close-up beauty portrait of a generic model with luminous hydrated skin, closed eyes, and hands near cheeks, without resembling any identifiable real person. Background: soft blush-to-pearl gradient with translucent water splash arcs and glassy cosmetic styling. Add a large headline stack on the left or upper left, three metallic circular benefit badges across the midsection, and a product container at the lower right with blank packaging and no brand name. Lighting: soft frontal beauty light plus rim highlights for wet-skin sheen. Materials: frosted glass, glossy cream jar, liquid splash, satin glow. Panel 3, bottom-left: a premium food-themed banner with sliced medium-rare steak on a dark hot plate, visible sear texture, steam, garlic chips, herbs, and ember-like bokeh. Use a deep charcoal, copper, and warm gold palette. Reserve a dramatic large headline area at upper left, a price or offer block at lower right, and one circular quality badge at upper right. Lighting: directional warm key light from upper left, strong specular highlights on meat juices, dark cinematic falloff, realistic smoke layers. Materials: cast iron, coarse salt, herb texture, glossy glaze, flame-lit reflections. Panel 4, bottom-right: an education or productivity-themed banner with a young adult studying at a desk beside a laptop and notebook, presented as a generic stock-style subject with no recognizable identity. Use a confident cobalt blue, white, and accent yellow palette. Place the main headline large at upper left, a horizontal subheading band below it, two simple line icons with short benefit text in the middle left, and a large circular achievement badge plus discount strip in the lower area. Lighting: bright indoor daylight with soft shadow edges, clean desk reflections, practical lifestyle realism. Materials: matte paper, brushed laptop surface, cotton shirt, laminated badge finish. Typography and layout rules: use bold Japanese-ad-inspired hierarchy but render all visible text as clean placeholder layout shapes or short generic ad copy only, except for the exact phrase "Launch Campaign" which must be clearly readable. Use oversized headline blocks, angled ribbons, circular badges, price-box placeholders, and icon clusters. Keep text zones crisp, intentional, and production-ready, with strong contrast and generous padding. Do not generate exact prices, brand names, social handles, addresses, phone numbers, certifications, or copied slogans. Avoid gibberish microtext; use tidy short placeholder lines where needed. Overall art direction: high-end digital ad creative, polished ecommerce-marketing finish, sharp retouching, high local contrast, subtle bloom, clean compositing, realistic materials, and commercially usable layout discipline. The image must look like a reusable ad-template case study rather than a copy of any one campaign. Reference-image policy: use the provided reference only as inspiration for grid composition, visual hierarchy, category contrast, badge placement, color energy, and commercial finish. Do not replicate the same people, exact wording, brand identifiers, numeric offers, package labels, or distinctive protected design details.
