日本 MNP 促销活动横幅

Goal: Create a bright square Japanese social media campaign banner advertising an MNP switching promotion for {argument name="campaign type" default="MNP limited campaign"}. Canvas: 1:1 square banner, 768×768 style, high-resolution, clean commercial ad design. Use a sky-blue radial burst background with pale rays from the center, dotted halftone texture near the edges, small sparkle stars, and about 28 colorful confetti pieces in pink, yellow, and blue around the border. Layout: Arrange the design in 5 stacked zones. Zone 1 is a dark royal-blue ribbon at the top with rounded rectangular center and pointed ribbon tails. Zone 2 is a large headline area with bold Japanese text. Zone 3 is the main offer amount, oversized and centered. Zone 4 is a white rounded information card with icons. Zone 5 is a large blue rounded call-to-action button at the bottom. Text content: Top ribbon text: {argument name="top ribbon text" default="MNP限定キャンペーン"}. Main headline: {argument name="headline text" default="乗り換えで"}. Main offer text must read {argument name="offer amount text" default="最大2万円還元"}, with the number and currency in bright yellow and the surrounding characters in deep blue. Information card text: {argument name="detail text" default="対象プラン申込で ポイント還元"}. CTA button text: "今すぐチェック". Small disclaimer centered below the button: "※表示はダミーです". Counted visual elements: Include exactly 1 top ribbon banner, 1 main headline, 1 oversized offer amount block, 1 white rounded information card, 1 CTA button, 1 smartphone icon on the lower left, 1 yellow circular gift icon near the center of the card, 1 group of gold coins on the right of the card, 1 white play-arrow circle inside the CTA button, and 2 yellow attention-burst marks flanking the CTA button. In the coin group, show exactly 3 stacked coin columns plus 1 large front coin marked with a capital "P". Visual style: Bold Japanese advertising typography, thick white outlines, blue drop shadows, glossy gradients, high contrast, celebratory telecom-promotion look. Use deep navy blue, royal blue, cyan, white, and vivid yellow as the primary palette. The main "2万円" should dominate the composition, with heavy outline layering: yellow fill, blue stroke, thin white outer glow, and soft shadow. Subject details: The smartphone should be tilted slightly left, with a cyan screen and a simple white two-person user icon. The gift icon should be a dark blue present symbol inside a yellow circle with tiny yellow sparkle marks above it. The CTA button should be a glossy rounded rectangle with a white border and soft shadow, containing a white circular play icon on the right. Constraints: Keep all text crisp and readable, centered, and in Japanese. Do not add logos, brand names, watermarks, QR codes, or extra copy. Maintain a polished Japanese mobile-carrier campaign banner aesthetic.
