Naive Marker PSA Poster Style

Design & animation notes

Preserve the core visual identity: A friendly hand-drawn public-service poster style built from chunky irregular marker outlines, oversized blue-bordered speech-panel typography, simplified cartoon people, flattened civic props, pastel paper backgrounds, warning-sign motifs, and intentionally naive perspective. 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. Variables to swap: subject, subject_action, product_or_prop, location (+6 more). Aspect ratios: 9:16 / 16:9.
