Baseball Papa T-Shirt Design

Create a clean text-based T-shirt design in **1080x1080 square format** with a **#D3D3D3 background**, **vector format**, **solid colors only**, and **built-in negative space**. Use the phrase **“Baseball Papa”** in bold friendly typography with a heartfelt family-baseball theme, combining classic block letters and slightly retro styling for an approachable and giftable look. Keep the design centered, high contrast, and fully inside the frame.
