Create a 1:1 concept sheet showing four text-free visual tiles for a {{THEME}} campaign: announcement, educational tip, reminder and call to action. Use {{SUBJECT}}, {{BRAND_PALETTE}}, a shared grid, lighting and motif; distinguish each tile by composition rather than random style changes. Leave practical blank copy zones. No words, numbers, logos, testimonials or claims. Keep the product, colours and subject proportions consistent; avoid clutter and stereotyped cultural elements.
Generate final assets individually in each required ratio. Add approved copy, CTAs and logos in a design tool.
