Grandfather and Granddaughter Height Chart

Create a nostalgic Japanese illustrated height-comparison poster titled {argument name="main title" default="祖父と孫娘"}, showing exactly two characters standing in profile facing each other across a central measuring ruler. The left character is an elderly grandfather labeled {argument name="grandfather name" default="昭夫"}, height 170 cm, wearing a muted brown traditional kimono with obi belt, tabi socks and sandals, slightly stooped, hands clasped behind his back, gray swept-back hair, calm gentle expression; place him on the left with a dotted horizontal guide line reaching the 170 cm mark. The right character is a small granddaughter labeled {argument name="granddaughter name" default="結衣"}, height 80 cm, wearing a soft pink smock dress over a cream skirt, pink shoes, dark brown ponytail tied with a red bow, hands behind her back, looking up at him; place her on the right with a dotted guide line reaching the 80 cm mark. Use a vertical 3:4 canvas with pale blue-green aged paper background, thin decorative border corners, sepia ink linework, warm watercolor wash, soft grain, and an old children’s book / vintage family record style. Put a tall central height scale from 0 cm to 200 cm with black tick marks and labels every 10 cm; emphasize 0 cm, 80 cm, and 170 cm in reddish brown. Add two parchment ribbon banners at the top: left reads 「おじいちゃん」 and right reads 「お孫さん」. Add two ornate cream information cards near the top: left card contains exactly 2 labeled fields, 「名前」 with the grandfather name and 「身長」 with 「170cm」; right card contains exactly 2 labeled fields, 「名前」 with the granddaughter name and 「身長」 with 「80cm」. Add one rounded thought/speech cloud above the granddaughter reading {argument name="speech bubble text" default="おじいちゃん、おおきいなぁ！"}. Include exactly 2 potted plant props: one leafy potted plant on a wooden stool at bottom left, and one small flowering plant in a wooden box at bottom right; scatter a few falling autumn leaves around the scene. Keep faces softly stylized and family-friendly, preserve all Japanese text exactly where specified, avoid modern UI elements, photorealism, extra characters, extra labels, or watermarks.
