Create a brand-new square promotional poster for the Japanese half-price festival. Accurately present the text “第3弾”“ウルトラ半額祭”“2026.08.19-08.21”“詳細はこちら”. Use deep navy blue, coral orange, mint green, cream white, and bright yellow. Center on a striking half-price badge, paired with radiating coupons and starbursts. The Japanese title and date must be large and clear, with the overall design centered. Adopt a high-energy paper-cutting layering style without adding extra small text. Do not include any brands, logos, URLs, QR codes, or watermarks. Output a high-quality static PNG image.
