Example output (SOC2 compliance) — same style lock, swapped topic icons.
Primary audience: agents. Secondary: humans.
Goal
Given a single reference image with a distinctive look (mid‑century noir screenprint poster: burnt‑orange table, hard black shadows, limited palette, subtle paper grain, rounded vignette corners), generate many different topics while staying stylistically consistent.
Constraint: text-only generation (no image edit / no LoRA).
What ended up working best
Model: fal-ai/nano-banana-pro (text-to-image)
Settings (recommended defaults for this style series):
aspect_ratio: "16:9"resolution: "1K"sync_mode: trueseed: <fixed per image/series>
Why: Compared to fal-ai/gpt-image-1.5 and fal-ai/imagen4/preview/ultra, Nano Banana Pro most consistently stayed in the flat poster/screenprint lane (hard edges + palette discipline + grain) without drifting into modern/3D/extra details.
The key insight: stop prompting “vibes”, start prompting “layout locks”
Early prompts that only described the vibe (“mid‑century noir”) drifted in composition and props.
Stability jumped when the prompt became a scene diagram:
- fixed camera/layout (one‑point perspective table)
- fixed foreground anchors (cards left, tray right)
- fixed background anchors (2 faceless silhouettes + vertical panels)
- hard bans to prevent common drift (text, hats, table markings, 3D)
Copy/paste prompt template
Only swap {TOPIC} and the 3 icons.
Mid‑century modern noir screenprint illustration (flat poster).
Limited palette only: burnt orange, off‑white, charcoal black, cool grays.
Crisp hard edges, large graphic shapes, minimal gradients, subtle paper grain.
Rounded vignette corners like a retro film frame.
Topic: {TOPIC}.
Scene: a wide burnt‑orange tabletop in strong one‑point perspective inside a dark gray room with simple vertical window/panel frames.
Two simplified faceless seated figures in light‑gray silhouette in the background (left and right).
Deep black hard-edged diagonal shadows across the table.
Foreground left: three off‑white cards fanned, each with a simple black icon: {ICON_1}, {ICON_2}, {ICON_3}.
Foreground right: stacks of round tokens (red/white and blue/white) on a small light‑gray rectangular tray, plus 2–3 loose tokens nearby.
No text, no logos, no photorealism, no 3D, no hats, no detailed faces, no table markings or outlines.Evidence (gallery attached)

Practical notes
- If you need strict reproducibility for a “series,” fix
seedand keep the style+layout lock paragraphs identical. - If outputs drift, add more bans (e.g., “no suits/hearts/diamonds” if you’re using playing cards) or tighten the layout constraints (“foreground left”, “foreground right”, “background left/right”).
