"Mia" 是带有 "COSY STREAM" 副标题的直播叠加边框，采用甜美蝴蝶结风圣诞风格。粉色缎带蝴蝶结、蕾丝、珍珠、樱桃、小圣诞树和礼盒环绕着奶油色亚麻质感的空白中央，外层是粉色糖果条纹边框。可以换成自己的频道名和标语，并把摄像头或游戏画面放在中间空白处。

Create a finished 16:9 coquette Christmas stream background for Mia. Keep the central webcam-safe area—roughly the middle 54% of the canvas width and 58% of its height—clear, pale and low-contrast, with no text, bows, lace, ornaments, frames or strong shadows crossing it. Use a smooth warm-cream card surface with subtle fine linen grain. Frame the outer edges with delicate pink-and-cream Christmas decorations: satin bows with softly gleaming folds and faint shadows, fine lace edging, a thin candy-stripe border, a few tiny sage-green hand-drawn trees, small cherries, hearts and scattered pearls. Keep the side decorations sparse and balanced, with ribbon tails trailing down the sides; leave generous breathing room around the webcam area. At the top centre, place a small, elegant scalloped cream name tag, fully outside the webcam-safe area. Set the exact text “Mia” as the clear primary text, with “COSY STREAM” beneath it in tiny, widely tracked neat capitals. Render “Mia” in delicate romantic high-contrast serif lettering: tall graceful forms, fine hairline serifs, softly tapering terminals, a light cursive slant and dainty swashes. Give the letters a soft satin sheen with faint pearlescent luster. Weave slender satin ribbon curls and a small bow into the lettering without obscuring any letter; add tiny round pearls at a stroke junction. Set “COSY STREAM” in small, legible deep-cherry lettering. Keep all other decorations around the perimeter, never inside the central clear zone. Use cream and blush pink as the dominant colours, deep cherry red only in small accents, and sage green only for the tiny trees. Gentle, diffused daylight; smooth card, subtle linen grain, delicate lace and soft ribbon shadows. Render only the two quoted text strings exactly; no extra words, symbols or watermark.
