"Design a sleek, modern invitation card celebrating the 18th anniversary of a high-quality, resilient, and courageous brand. The card should feature the following words prominently: Leadership, Quality, Resilience, Integrity, Courage. Use a refined, elegant gold and deep blue color palette to symbolize excellence and strength. Include subtle geometric and abstract elements to convey resilience and courage. The typography should mix serif fonts for Leadership and Quality, and bold modern fonts for Resilience and Courage. Surround the design with a gold frame or circular accent to symbolize unity and completeness. The overall tone should be professional, inspiring, and empowering, with minimalist illustrations or icons (like a crown, anchor, shield) subtly representing the key values."
