Cute Tabby Cat LINE Sticker

Create a cute LINE sticker-style illustration on a square white canvas, featuring one chubby tabby cat sitting happily on one soft beige cushion. The cat has {argument name="fur color" default="warm brown and cream tabby fur"}, darker rounded stripes on its head, body, legs, and thick curled tail, closed smiling eyes, tiny whiskers, blush-like cheeks, and one front paw raised as if kneading or waving. Use a soft kawaii digital illustration style with clean dark-brown outlines, gentle cel shading, rounded forms, and a minimal transparent-sticker feel against a plain white background. Place exactly one short caption centered below the character in small black Japanese text: {argument name="caption text" default="ふみふみ"}. Keep the composition simple and centered with generous white space, no extra props, no border, no watermark, and no additional text.
