Japanese Pediatric Disease Infographic

Goal: Create a friendly Japanese medical explanation infographic for parents about {argument name="topic title" default="手足口病とヘルパンギーナ"}, suitable for use in a pediatric clinic consultation room.

Canvas: Vertical portrait flyer, warm off-white paper background, soft hand-drawn watercolor style, rounded corners, pastel colors, clear black handwritten Japanese text. Add small decorative confetti marks around the title. Overall look should be cute, reassuring, and easy to understand.

Layout: Use exactly 5 stacked rounded rectangular information panels, each with a large numbered circle on the left. Panel 1 has a pink border, panel 2 blue, panel 3 yellow-orange, panel 4 green, panel 5 orange with a scalloped decorative border. Keep generous margins and make all text large and legible.

Title: At the top, write 「手足口病とヘルパンギーナ」 in large dark brown handwritten lettering with a pink wavy underline.

Panel 1, number 1, pink: Write 「手・足・口に小さな水疱、おしりにも」. Include exactly 4 medical illustrations in a row: an open palm with small red blisters, a sole of a foot with small red blisters, an open mouth/throat with red spots, and a diapered bottom/thigh area with red spots. At the bottom add a small sun icon and the note 「夏〜秋に小さい子に多い」.

Panel 2, number 2, blue: Write 「原因はコクサッキーウイルス」 and smaller text 「ありふれたかぜのウイルス」. On the right draw exactly 1 cute round blue virus mascot with tiny spikes, eyes, a smiling mouth, and small motion lines.

Panel 3, number 3, yellow-orange: Show a simple Venn diagram with exactly 2 overlapping large translucent circles: left circle pink, right circle light blue, overlap pale green. Left circle text: 「のどの奥に白い水疱→ヘルパンギーナ」. Right circle text: 「手のひら・足のうらに発疹→手足口病」. Under the circles write: 「原因ではなく『どこに出たか』でつけた病名。ヘルパンギーナでも全身に発疹が出ることがあり、厳密には区別できない」.

Panel 4, number 4, green: Write 「特効薬なし・対症療法」 and smaller text 「約1週間で治る」. Include exactly 4 supportive-care illustrations: a glass of water, a sleeping child tucked in bed, a digital thermometer showing 36.6°C, and a smiling child in a green striped shirt raising one fist.

Panel 5, number 5, orange: Headline in large orange text: 「登園の目安」. List exactly 2 numbered conditions: 「① 熱がない」 and 「② 普通にご飯が食べられる」. Add a large emphasized orange message: 「発疹が残っていても 普通の生活・登園OK」. Smaller explanatory text at the bottom: 「ウイルスは治った後も長く出続けるので、発疹が消えるまで待つ意味はありません」. On the right draw a cheerful preschool child wearing a yellow hat, blue backpack, striped shirt, blue shorts, and sneakers, running or waving toward a small school building with flowers.

Constraints: Use exactly 5 numbered panels and the exact Japanese text above. Do not add extra sections, extra medical claims, logos, watermarks, QR codes, or English translations. Keep the illustration soft, pediatric, non-scary, and clinically clear.
