Create a rectangular envelope design with the following features: 1. Header: Use a solid blue border at the top with a simple, modern font for the title "RECIPIENT" in white text. 2. Main Section: Leave space for handwritten details, such as a recipient's name and address, with a large, clear font. 3. Bottom Section: Include a website link placeholder in a smaller, italicized font, using a muted gray color for a subtle appearance. 4. Add an illustration of a small envelope or package on the left side of the envelope to indicate mailing. 5. Remove any brand references or logos, focusing on a clean, minimalistic design that maintains professionalism. 6. Use a light beige background for the entire envelope for a warm and inviting look.
