Cute Father’s Day Instagram Cover

Goal: Create a cute square Instagram carousel cover post for {argument name="audience" default="育児垢ママへ"}, encouraging moms to prepare early for Father’s Day. Use a warm hand-drawn Canva-like style with Japanese lettering. Canvas: Square 1:1 vertical social media post, cream/off-white paper background with a thin rounded pink border inset from the edges. Soft pastel palette: blush pink, warm brown, peach, cream, and light orange. Pencil-crayon texture, watercolor shading, rounded friendly shapes. Layout: At the top center, place a pink ribbon banner with stitched details containing the text 「育児垢ママへ」 in dark brown handwritten Japanese. Beneath it, add the main headline in very large dark brown brush lettering across two lines: 「父の日、」 and 「まだ早いと思った？」. To the right of the headline, add a white cloud speech bubble outlined in pink with the text 「6月21日だよ」. Below the headline, place a wide rounded coral-pink pill-shaped callout bar with white handwritten text and small radiating accent marks: 「仕込むなら今がベスト」. Main illustration: Bottom half shows a cheerful mother and two children rendered as adorable squirrel-like characters, centered and sitting together. Count exactly 3 characters: 1 mother in the middle with orange hair in a high bun, squirrel ears, pink cardigan, holding a pink smartphone with a small heart on the back; 1 small girl on the left with orange pigtails, a pink bow, pink top, smiling and leaning in; 1 small child on the right with squirrel ears, striped cream-and-yellow shirt, large fluffy orange squirrel tail behind them, smiling toward the phone. All have round faces, rosy cheeks, big glossy eyes, tiny noses, and happy open mouths. Decorative elements: Add exactly 8 pink heart/sparkle decorations around the poster: 1 large heart near the top left, 2 sparkles near the top right, 1 heart on the left above the memo, 2 small hearts/sparkles around the left-middle area, 1 small heart to the right of the characters, and 1 sparkle on the far right. Keep them light and hand-drawn. Bottom details: In the bottom-left corner, place a tilted white memo card taped with pink washi tape. It must include a small heart and the word “memo” in pink, plus Japanese text in dark brown: 「育児垢ママ向け」 on one line and 「投稿スケジュール」 on the next. Along the bottom center, add exactly 10 small carousel progress dots: the first dot filled coral pink, the remaining 9 outlined or pale. In the bottom-right corner, add a large coral-pink stitched circle badge containing the white number {argument name="slide number" default="1"}. Text content to preserve exactly: 「育児垢ママへ」, 「父の日、まだ早いと思った？」, 「6月21日だよ」, 「仕込むなら今がベスト」, 「memo」, 「育児垢ママ向け」, 「投稿スケジュール」, and {argument name="slide number" default="1"}. Constraints: Make the typography look hand-lettered, not like a standard font. Keep the design soft, cute, approachable, and readable on Instagram. Avoid photorealism, hard shadows, clutter, extra characters, extra carousel dots, watermarks, or logos.
