494歴史まんが学習ポスター

Generate exactly ONE finished Japanese educational comic infographic poster now, not an explanation. Canvas: 出力サイズは1080×1440ピクセル、3:4の縦型SNS投稿にしてください。; default 3:4. Flat full-bleed artwork, no mockup, no contact sheet, no code, no follow-up task.

Topic: 【テーマ】. School level: 【学年】. Mood: 【雰囲気】. If blank or automatic, use 韓国の伝統紙 / 小学4年生 / 温かい昔の工房. Explain one topic only. If the topic concerns a real person, focus on verified objects, events and places without drawing their portrait. Any named fictional guide is Haru, an original small nonhuman character with no resemblance to an existing character.

Fixed result structure: one large subject illustration and title, exactly three numbered narrative comic panels, one chronological band, exactly five numbered illustrated key facts (01–05). Adapt vocabulary and sentence length to the school level. Put the school level and mood in a compact subtitle. The heading is Haruと学ぶ一枚. Keep panels varied in scale and viewpoint. Use short complete factual captions on solid light text areas. Integrate tiny diagrams and object details rather than decorative filler. Maintain one consistent visual treatment within each poster.

Mood treatments within this fixed educational comic format: warm traditional workshop = amber/russet/indigo textured ink and woodcut; quiet museum = jade/ivory delicate watercolor and ink; exciting expedition = vivid orange/teal bold adventure comic and fine halftone; bright science classroom = sky blue/lemon/lilac gouache cut-paper comic. Mood changes the visual treatment, never the result type or section counts. For other supplied moods, derive an equally coherent original treatment. No artist or studio imitation.

Before drawing, verify facts using museum, public education or scientific institution web sources. Verify chronology and each of the five facts. Do not fabricate dates, quotes, firsts or records. If web verification is unavailable, use only well-established facts with no numeric dates. Historical subjects get a chronological timeline with verified dates only; craft and science subjects get an ordered process band instead of invented years. Cyclic topics show a return connection; do not imply that every water molecule follows the same path. Show different prehistoric periods in separate panels, not a falsely simultaneous scene. No verification notes or source disclaimers printed in the artwork.

For the default topic, the three panels are fiber preparation, sheet forming with a papermaking screen, and drying. The process is fiber preparation → sheet forming → drying. The five facts are that this is traditional Korean paper; paper mulberry (Broussonetia) bark is a material; long fibers interlock; drainage and drying are required; it has uses including books and window coverings. Translate naturally into Japanese. Do not mechanically reuse these facts for another topic.

Typography: natural Japanese only, large sharp high-contrast lettering, Reserve the upper 12% and lower 15% of the canvas for illustrations only, with absolutely no lettering or numerals in either band. Place the heading, title, subtitle, all three panels with captions, the process band and all five facts entirely within the middle 60% of the canvas (y=18% to y=78%). Use concise one-sentence captions so every text block fits in this region. Keep every letter and numeral below y=18% and above y=78%, leaving a buffer beyond the required safe margins. No tiny paragraphs, cropped words, empty balloons or extra labels. Proofread every character, numeral and arrow before rendering. Count three panels and five facts. Avoid real people, celebrity likeness, real brands, logos, trademark products, existing characters, watermarks, signatures and copied artifact patterns. Invent original decoration and fictional object designs while preserving the factual teaching structure. Return only the complete image.
