Minimalist Mother's Day Floral Wallpaper

Create a vertical minimalist Mother’s Day smartphone wallpaper on a warm off-white paper-textured background, centered composition with lots of negative space. At the top, place very large elegant black Japanese calligraphy reading {argument name="character name" default="かのん"}, with a soft hand-brushed look. Directly below it, add the main serif uppercase greeting {argument name="main greeting" default="HAPPY MOTHER’S DAY"} in black, classic editorial typography. In the center, arrange one realistic pressed-flower style bouquet of carnations and eucalyptus, stems tied visually by overlapping and tapering downward; include 14 visible carnation blossoms in pink, coral, peach, orange, cream, pale yellow, and red tones, plus 8 small green flower buds, slender dark green stems, and rounded eucalyptus leaves spreading gently left and right. Below the bouquet, add a second large centered serif uppercase line reading {argument name="lower greeting" default="HAPPY MOTHER’S DAY"}. At the bottom left, include three small black sans-serif lines: “Gratitude & Love”, “Always cherished”, and “HAPPY MOTHER’S DAY”. At the bottom right, include two small black sans-serif lines: “TO THE MOST WONDERFUL MOTHER” and {argument name="signature name" default="KANON"}. Use a refined Japanese greeting-card aesthetic, natural daylight, delicate shadows around the flowers, realistic botanical detail, clean premium magazine layout, no border, no extra objects.
