Wide YouTube channel banner, 3D Pixar style: a cozy storybook cottage garden at golden hour with a little round wooden door house, flowers, a white picket fence, soft clouds. In the CENTER horizontal band: the grey tabby kitten Button (folded ear, yellow scarf) from reference 1 waving, the fluffy cream Mama Cat in blue apron from reference 2 holding a basket of berries, and the tiny brown mouse Pea with green leaf hat from reference 2 sitting on a flowerpot. Characters stay inside the central 60% width and middle 30% height; leave clean soft sky on the LEFT part of the central band for a title. Warm, joyful, no text, no letters.
