Design a social media graphic promoting a fast, efficient travel insurance service, emphasizing the phrase ‘Travel insurance in just 1 hour’ in clean, bold, sans-serif font, centered prominently. The layout is a square, high-contrast composition, with a professionally dressed, approachable representative character illustrated in a vector style on one side. The background features a smooth gradient in warm tones, enhancing contrast with cooler accent colors in the representative’s attire. Use subtle, minimalist icons like airplanes or passports as background accents, enhancing the travel theme without overwhelming. Include a rounded-edge CTA button labeled ‘Call Now’ in high contrast (e.g., white on navy blue) positioned clearly below the main text. The overall feel is modern, professional, and engaging, using color and contrast theory to maximize readability and impact for mobile viewers."
