Rain Lodging Picture Book Prompt Sheet

Goal: Create a horizontal illustrated concept sheet for a picture book page, showing exactly 6 prompt variations for the theme {argument name="theme" default="rain lodging"}, with Japanese handwritten-style headings and captions. Canvas: Wide 16:9 off-white paper background, like a printed presentation page. Use a soft watercolor picture-book style, gentle rain atmosphere, quiet discovery, warm muted colors, delicate ink outlines, natural paper texture, no photorealism. Main title: At the top left, write in Japanese: 「絵本の1ページ：テーマ『雨宿り』プロンプト6パターン」. Use casual handwritten black text. Layout: Arrange exactly 6 rectangular watercolor image panels in a clean 3 columns × 2 rows grid. Each panel has a numbered Japanese title above it and a short two-line Japanese caption below it. Keep generous margins, consistent spacing, and the feel of a design board or prompt-comparison sheet. Panel 1: Title 「1. カエルの目線：葉っぱの下は、小さな世界のステージ」. Image: low frog-eye viewpoint under a large green leaf during rain; raindrops bead along the leaf edge, a green frog sits beside a small snail and tiny mushroom on wet ground, soft forest background and reflected water. Caption: 「大きな葉っぱの下は、ぼくの特等席。雨の音が、ステージの拍手みたいにきこえるよ。」 Panel 2: Title 「2. 傘の内側から見た世界」. Image: view from inside a transparent umbrella, with umbrella ribs visible as strong black lines; blurred silhouettes of people and pastel umbrellas outside in the rain, and a small hanging teru teru bozu charm near the right side. Caption: 「傘の内側は、ぼくだけの小さな部屋。雨の粒が、まるで窓の外の絵みたい。」 Panel 3: Title 「3. 建物のすきまから見える、雨の通り」. Image: narrow dark stone passage or alley framing a rainy street beyond; a small child or figure with a red umbrella walks away in the distance, city buildings softened by rain, ivy on the wall. Caption: 「ぼくは、このすきまがだいすき。だれかの物語が、雨というしおりを通りすぎていく。」 Panel 4: Title 「4. 水たまりの中に映る、もうひとつの世界」. Image: reflective puddle on a city path showing an upside-down rainy world: buildings, umbrella silhouette, sky, leaves, flowers, and manhole details around the puddle edge. Caption: 「水たまりって、空への入り口かも。うつった世界は、少しだけ静かで、やさしい色をしてる。」 Panel 5: Title 「5. 雨粒になって見た、いつもの風景」. Image: close-up of hanging raindrops, with one large central droplet containing an inverted miniature village reflection; blurred rooftops and greenery in the background, shallow depth of field, sparkling rain. Caption: 「ぼくは、空からの小さな旅人。みんなのところへ、そっと降りていくよ。」 Panel 6: Title 「6. 動物たちと一緒に雨宿り（屋根の下の小さな劇場）」. Image: under an old tiled roof or eave, exactly 4 animals shelter together from the rain: a tabby cat, a rabbit, a small round bird, and a mouse. Warm hanging lantern light, potted flowers on the side, raindrops falling from the roof edge, cozy theatrical composition. Caption: 「雨の日は、みんなでひとやすみ。屋根の下は、やさしいおはなしがうまれる場所。」 Footer note: Along the bottom left, write in Japanese: 「※ どのページも、やさしい光・静けさ・発見を感じる雰囲気で。」 Constraints: Include exactly 6 panels and exactly the 4 animals listed in panel 6. Keep all visible text in Japanese as specified, handwritten and legible. Avoid extra logos, watermarks, modern UI elements, or additional panels. The overall mood should be gentle, poetic, rainy, quiet, and suitable for a children’s picture book concept sheet.
