Create a 1:1 square advertising poster that matches the uploaded reference advertisement's layout density, visual rhythm, and information-rich service-promotion style. Make it a fictional Japanese babysitter matching app campaign, not a real brand. Use a bright city aerial background, a friendly adult caregiver character holding a child, and layered promotional UI blocks. Include a large Japanese headline, a short service description, a section for five key benefits with simple line icons, a large discount offer panel, a coupon-code box with fictional text, a step-by-step usage flow, three user testimonial cards on the right, and a bottom app-download strip with a fictional app logo, phone mockup, and placeholder QR-code blocks. Use a clean pink, white, yellow, and soft-blue palette, rounded cards, friendly family-service mood, and high information density while keeping the hierarchy readable. The text can be approximate generated Japanese but should look like a believable service advertisement; mark it for later copy review. Avoid real App Store or Google Play badges, real QR codes, real company logos, real service names, copied brand marks, misleading childcare claims, identifiable real people, and extra watermarks other than the Pix2 preview watermark. Output aspect ratio: 1:1.
