9分割ヒントカルーセル

Create a 3:4 vertical poster laid out as a strict three-by-three grid designed to be sliced into nine standalone social-carousel cards. Give every cell a clear boundary with visible gutters or thin borders so nothing is lost when the image is cut, and keep each cell's content fully centered, well away from the dividing lines. Make the first cell the cover card: the biggest, most eye-catching title with a short save-worthy subtitle and the richest illustration. Fill the remaining eight cells with numbered tip cards, each carrying a short bold heading, one or two lines of body text, and a small cute skeuomorphic illustration accent that matches the tip. Use a soft healing palette of cream white, light beige, oat, and pale caramel with dark-brown text, comfortable white space, and tidy magazine-grade typography that stays large and readable at feed size. Take the topic, the tips, and their wording from the user request, and render all on-card text in the request's language with accurate, non-garbled glyphs. Keep illustration style, spacing, and type perfectly unified across all nine cells so each also works alone. No watermarks, logos, platform icons, or cheap cluttered marketing styling.
