"Happy Halloween"是一张可爱贴纸风的万圣节壁纸，中央留有奶油色空白。紫色和橙色的圆润字体位于左侧，周围有微笑的幽灵、南瓜灯、熟睡的黑猫、蝙蝠、弯月、糖果和小星星。你可以把问候语换成自己的文字，如派对名称、日期或孩子的名字，也可以调整角色位置。

Create a finished 16:9 cute Halloween desktop wallpaper for a laptop screen. Set the exact text “Happy Halloween” once, small but clearly readable, on the left in the open space. Use kawaii rounded display letters: wide, short proportions, softly weighted strokes, generous spacing, large open counters, and perfect bubble-shaped terminals. Give the lettering smooth polished toy-plastic surfaces with gentle, small specular highlights. Surround the canvas edges with a playful die-cut sticker frame: plump smiling ghosts with dot eyes and rosy cheeks, friendly jack-o’-lanterns, and a sleepy black cat, with a few tiny bats, wrapped sweets, stars and a crescent moon as supporting accents. Give every character a clean white sticker border, thick soft rounded outlines and smooth flat fills. Keep the characters primarily around the perimeter; preserve generous calm cream negative space through the center and around the small left-side greeting. Make the figures distinct and comfortably spaced, never covering the text or crowding the screen. Soft even light, no dramatic shadows, only subtle highlights. Add faint hand-drawn paper grain to the warm cream background. Use cream, peach and soft lilac with pumpkin-orange and black characters and small pink blush accents. Sweet, friendly, simple and polished, like a kids’ Halloween wallpaper. Render no other words, lettering, logos, interface elements or watermark.
