報稅倒數再行銷廣告（極簡企業風）

prompt

Create a 4:5 Facebook retargeting ad image for an accounting firm's tax season countdown. Ultra-minimal corporate style: a deep navy background with subtle paper-grain texture, a giant white numeral showing {days_left} filling the right half of the frame, underlined by a thin gold rule. Add a small outlined calendar icon marked {deadline_date} near the numeral. Keep the entire left half as a clean safe margin for ad copy about {service_name} and the firm location {firm_city}. Soft studio lighting, generous negative space, crisp sans-serif feel, conveying urgency with calm professionalism rather than alarm. No clutter, no stock-photo people.
