AI Prompt for Retro Japanese Hot Spring Illustration with Capybara

"Goal: Create a whimsical Japanese hot spring membership card profile design for {argument name="character name" default="tabo"}, styled like a vintage printed certificate with cute animal illustration. Canvas: Horizontal membership card, wide 16:9 ratio, warm aged cream paper background with subtle grain, stains, and slightly worn edges. Use a double-line ornate gold border with clipped decorative corners and small Japanese cloud motifs in muted gold. Layout: Large top headline reads “ONSEN MEMBER CARD” in a Western vintage serif font, dark brown with gold shading and engraved texture. Centered above or between the words is a small red hot spring steam icon. Under the headline, add Japanese text “温泉会員証” with symmetrical gold flourishes on both sides. The main illustration fills the middle: a smiling capybara soaking in an orange-red hot spring, wearing a folded white towel on its head, cheeks slightly rosy, one eye happily closed. Behind it are rocky volcanic hot spring scenery, steam wisps, and two volcanoes: 1 smaller smoking volcano on the left and 1 larger erupting volcano on the right with orange lava. In the bath water, include 1 small capybara head in the left-middle background. The water is rendered as swirling orange and red crayon-like rings. Visible labeled elements: Include exactly 5 major text/mark areas: 1 large English title “ONSEN MEMBER CARD”; 1 Japanese subtitle “温泉会員証”; 1 vertical red plaque on the left with white Japanese text “極楽湯めぐり”; 1 circular red stamp on the lower right with Japanese text “入浴済” and a small steam icon; 1 bottom information strip divided into two boxed fields. In the bottom left field, show small label “お名前” and large handwritten Japanese name {argument name="display name" default="たぼ"}. In the bottom right field, show small label “会員番号” and membership number {argument name="membership number" default="26-0410-2680-26"}. Visual style: Hand-drawn colored-pencil and crayon texture, nostalgic Showa-era Japanese travel-ticket aesthetic, warm browns, reds, oranges, cream, and muted gold. Keep lines slightly imperfect and tactile, as if printed on thick washi paper. Add small decorative plum blossom icons in gold and red near the lower corners. Constraints: Keep the design readable as a single card, with no photorealism, no modern UI elements, no extra logos, and no additional text beyond the specified 5 text/mark areas."
