Create an image in naive-marker-psa-poster-style.
Aspect ratio: {ASPECT_RATIO}.
Scene: {SUBJECT} {SUBJECT_ACTION}, featuring {PRODUCT_OR_PROP}, in {LOCATION}. Include {BACKGROUND_ELEMENTS}. Style the characters with {WARDROBE_STYLE}.
Illustration: make a finished raster poster, not a photo, SVG, UI mockup, or clean vector icon set. Use thick uneven black marker outlines, flat hand-colored fills, rounded stroke ends, subtle paper grain, marker scuffs, imperfect edges, and low-polish scanned-poster softness.
Layout: reserve the upper half or upper band for a huge rounded speech-panel sign with a thick marker-blue border and off-white interior. Put "{MAIN_TEXT}" inside the sign as massive rough black block letters. Add "{SECONDARY_TEXT}" as a small rounded red or blue capsule label near the headline.
Characters and setting: place one or more simplified cartoon people in the lower half with playful scale distortion, oversized hands, signs, or props, and intentionally naive proportions. Build the environment from flat doodled public-scene icons: tiny buildings, signs, cones, grass tufts, arrows, rocks, labels, alert marks, and simple yellow ground patches.
Color and mood: use pale blue background, cream panel, marker blue frame, coral red accents, warm yellow ground, soft skin pink, grass green, chalk gray, and deep black ink. Keep the poster friendly, instructional, childlike, approachable, and lightly comedic. Include {ACCENT_SYMBOL} as a simple graphic accent.
Avoid: watermarks, usernames, creator IDs, platform logos, QR codes, app UI, signatures, copied reference text, copied reference characters, red telephone, legal theme, date range, no-access sign, exact layout, brand logos, licensed characters, recognizable people, photorealism, 3D render, glossy vector art, clean corporate icon set, gradient lighting, airbrush shading, thin elegant line art, realistic anatomy, correct architectural perspective, long paragraphs, dense fine print, and dark cinematic mood.
