"SUS" 是一个 Twitch 聊天表情，采用鼓鼓的卡通风格。三个带粗深色描边和白色贴纸边的青柠绿字铺满纯白方块，圆润又微微歪扭，透着搞笑又怀疑的劲儿。可以换成你自己的三字母反应词和颜色。

Create a finished 1:1 Twitch chat emote, designed to remain instantly readable when reduced to 28 × 28 pixels. Render only the exact text “SUS”. Center the word as one large, compact sticker graphic, filling about 76% of the square with generous clear margin. Custom lettering: extra-bold, squat uppercase forms with subtly uneven, wobbly contours, narrowed horizontal proportions, and slightly pinched inner counters to give the letters a squinty expression; keep each letter clearly distinct. Solid vivid lime-green faces with small, flat lighter-lime highlight patches and darker-green lower-edge accents; no gradients. Surround the entire word with one very thick, smooth, near-black outline, plus a narrow clean white outer keyline so it separates from both light and dark chat interfaces. Flat, crisp vector-like finish, high contrast, clean edges, no fine detail, no texture, no shadow, no extra symbols or decoration. Plain solid warm-white background. No other text.
