Use when the user wants to create app store screenshots, promo graphics, marketing images, launch visuals, OG/social cards, or "宣传图" for an app — and wants exact platform sizes exported as PNG/JPG/WebP/AVIF and/or true vector SVG. Renders designed templates with a real browser (Playwright) and rasterizes vectors with resvg.
