SaaS 展場攤位傳單（等距科技插畫風）

prompt

Design a vertical A5 handout flyer for a SaaS product called {product_name}, built for a tech expo booth. Top half: a clean isometric illustration of a dashboard floating above connected devices, rendered in {brand_color} gradients on a deep navy background. Center: bold sans-serif headline stating {key_benefit} in under six words. Lower third: three small feature icons in a row, plus the text 'Visit booth {booth_number}'. Reserve a clean white band across the bottom 15% for QR code, pricing and contact details to be overlaid later. Flat vector style, generous white space, crisp edges, no photographic textures. Portrait 3:4 ratio, print-ready composition.
