"Create a beautiful, heartwarming birthday card designed for a mother, with a focus on warmth, love, and celebration. The card should feature a soft pastel color palette, incorporating shades of pink, lavender, and light gold. In the center of the card, there should be a large, elegant Korean text that reads '생일 축하해요, 엄마! 사랑해요!' written in a flowing, cursive style. Surrounding the text, add delicate floral illustrations with roses, peonies, and baby's breath. The background should have a subtle gradient with a gentle texture, like watercolor or soft fabric. Add a few golden accents, such as a thin border or small sparkles, to give the card a touch of elegance and luxury."
