Elegant Carnation Mother's Day Wallpaper

Create a minimalist vertical Mother's Day wallpaper poster on a warm ivory paper background with soft natural shadows and lots of negative space. In the center, arrange a delicate bouquet of carnations with 5 visible flower heads: 1 large pale pink carnation near the upper left, 1 closed pale pink bud at the upper center, 1 peach carnation in the middle, 1 soft yellow carnation on the right, and 1 pink carnation near the lower center; include slender green stems, narrow leaves, and 3 small green buds, rendered as realistic pressed-flower photography with gentle studio lighting. Overlay very large elegant black Japanese calligraphy reading {argument name="main Japanese word" default="かのん"} across the upper-middle of the bouquet, then place a refined high-contrast serif headline across the lower-middle reading {argument name="main headline" default="HAPPY MOTHER’S DAY"}, with thin Didot-style letterforms and graceful curves. Add 4 small letter-spaced message blocks in black: top left says {argument name="top left message" default="To the most wonderful mother, thank you. With all my love."}, top right says {argument name="top right message" default="MOTHER’S DAY THANK YOU ALWAYS."}, bottom left says {argument name="bottom left message" default="You are my love, my strength, my everything."}, and bottom right says {argument name="bottom right message" default="Wishing you a beautiful day filled with love and happiness."}. Keep the composition airy, elegant, feminine, modern Japanese editorial style, with crisp typography, realistic flower texture, subtle shadows, and a premium greeting-card aesthetic.
