Ретро-поп постер для путешествий и семейного отдыха

A bold, energetic travel poster in a retro pop-art collage style, vertical composition. The background is a vivid saturated orange with layered textured paper grain, halftone dots, paint splatters, rough brush streaks, diagonal stripe patterns, checkerboard accents, abstract blobs, and hand-drawn white doodles including 4 starburst shapes, 3 zigzag marks, and several short accent strokes. Dominating the upper half is the huge word {argument name="headline text" default="Go!"} in oversized comic-style hand-lettered typography, white with rough sketchy brush outlines, slight 3D depth, and yellow paint accents, ending with a dramatic exclamation mark. In the lower right and center foreground, show a cheerful family of 4 on vacation as cutout photo-style figures with thick white sticker outlines: 1 adult man, 1 adult woman, 1 boy, and 1 girl. All four are looking upward and pointing excitedly toward the upper left or upper right, conveying enthusiasm and motion. The man stands on the right, tall, wearing a light cap, white T-shirt, open yellow overshirt, blue jeans, and a backpack strap visible, with one arm raised straight up and finger pointing. The woman stands slightly left of him, wearing a straw hat and a loose white blouse, smiling and pointing upward. In front, the boy wears dark sunglasses, a light jacket over a yellow shirt, and a backpack, pointing diagonally upward. Beside him, the girl wears a straw hat and a yellow-and-white striped top, pointing upward while holding or standing close to a bright yellow hard-shell suitcase with visible telescoping handle in the bottom-right corner. Use a warm palette of orange, yellow, and white with high contrast, playful summer-travel mood, dynamic diagonal flow, poster-like advertising energy, mixed media look combining photographic people and illustrated graphic design.
