Create an original near-square English spring sale poster in fresh green, cream, and coral, with a bold central offer, one compact coupon code strip, and a simple button. Text: “SPRING SALE”, “EXTRA 25% OFF”, “FOR VIP”, “CODE: BLOOM”, “SHOP NOW”. Keep the layout clean with two small leaf accents only. No brand, watermark, QR code, website, non-English text, or random tiny text.
