Prompt: \"Design a delightful birthday cake with a smooth, creamy texture. The cake should be adorned with a combination of playful and sophisticated decorations, including fine piping, delicate edible gold leaf accents, and a scattering of small, colorful sugar pearls. At the center of the cake, in stylish and legible cursive, it should say 'Hi Ryan.' The cake should be a multi-tiered creation, with each tier featuring a subtle gradient of soft hues. The background should be soft and blurred to keep the focus on the cake's intricate details.\"
