VARIABLES

GRID_SIZE: <number of panels, e.g. 4, 6, 9>
GRID_LAYOUT: <layout format, e.g. 2x2, 3x2, 3x3>
COLOR_PALETTE: <brief description of dominant colors and mood, e.g. muted pastels, monochrome, warm tones>
STYLE: <illustration style, e.g. hand-drawn, painterly, storybook, flat graphic>
MOOD: <overall emotional tone, e.g. happy, calm, sad, nostalgic, ironic>
NARRATION_MODE: <visual | visual+text | text-led>
SIGNATURE: <optional signature text and placement, e.g. "Aimi Koda, bottom-right"; if empty, do not add a signature>
INSTRUCTIONS
1. Create a square comic-style illustration using GRID_LAYOUT with equal spacing and clean borders.
2. Interpret TOPIC as the narrative anchor and invent a short story that unfolds across the panels.
3. If CHARACTERS is provided, strictly follow it; otherwise invent character(s) that naturally fit TOPIC.
4. Keep character identity, proportions, and visual traits consistent across all panels.
5. Decide the camera progression yourself in a way that best serves the invented story.
6. Decide the background behavior yourself, keeping visual coherence across panels.
7. Decide the lighting approach yourself, choosing what best fits MOOD and STYLE.
8. Decide the overall detail level yourself and keep it consistent across all panels.
9. Apply COLOR_PALETTE consistently, allowing subtle variation when narratively useful.
10. Let MOOD influence composition, pacing, expressions, and visual rhythm across panels.
11. Follow NARRATION_MODE strictly:
- If visual: include no text inside panels and rely entirely on imagery.
- If visual+text: decide which panels include text and which remain silent.
- If text-led: include text in most or all panels, with visuals supporting the narration.
12. When text is used, place it inside panels in a comic-appropriate way, such as captions, thought text, or minimal dialogue.
13. Write short, natural, story-driven text that advances the narrative implied by TOPIC and MOOD.
14. Do not force text into every panel unless NARRATION_MODE is text-led.
15. Ensure the sequence forms a clear beginning, middle, and end through visuals, text, or both.
16. If SIGNATURE is provided, add it exactly as specified, placed discreetly without distracting from the illustration.
17. Avoid unnecessary elements and visual noise.
18. Ensure the final output reads clearly as a single cohesive multi-panel comic illustration.
